FYI: BUG in SATA Promise 300 TX4 (2.6.24 - 2.6.27-3) w/Linux
Subsystems (2)
FYI -- ever since I switched to using SATA, I've not had a stable kernel. Sys uptime went from near infinite (striking planned take downs), to less than a week consistently. I'd been using the Promise 300 TX4 with 1-2 Seagate drives. (PDC40718, rev 02).
Finally an explicit problem regarding that controller under Linux, with it timing out a drive returning from suspend during 'SMART' operations, got a suggestions from the community (Tnx, Tejun Heo) to try a _cheaper_ but better featured Silicon Image controller (SiI 3124 Sata).
Not only did it NOT have the SMART problem (that would hang the drive or machine), but my random hangs seem to have gone away.
My main server has been up nearly 21 days now on 2.6.27-3 SMP (vanilla-i386).
I'd had problems with the ranging in kernels going back to 2.6.24 or so when I had first tried adding SATA to the system.
So Tnx again to Tejun --
and NOTE: the card or driver (or both) for the Promise 300 TX4 isn't stable for production use -- and has a repeatable problem of timing out some drives before it can spin-up from standby (just the drive -- not the computer). The error logically removes the drive from the system until the next boot (unplugging, and replugging in the SATA cable on the drive would hang the machine within 5 seconds of replugging in the cable). Not an instant, hang as might indicated a HW upset plugging in cable, but a couple second delay after plugin -- before keyboard would lock up -- pointing toward the software trying to re-add+initialize the drive.
Needless to say, I'm only using the Sil controller now, and things are stable.

Yeah, I'm quite fond of the controller. Except for the bandwidth limit due to limited number of postable requests which shows up only when multiple drives are attached to a single port via PMP, I can't think of anything bad about it.

Some promise controllers seem to suffer transmission problems when combined with certain drives, which often show up as timeouts. The hardreset of sata_promise wasn't as robust as it should have been and in some cases it wasn't able to recover a link after error condition causing the system to lose drive after such events. The hardreset problem was fixed recently by Mikael Pettersson. Can you please try 2.6.28-rc5 and see whether sata_promise still loses drives after failures?
Mikael, I think the hardreset fix is worthy including into -stable. It should be safe for -stable too, right?
Thanks.

The hardreset fix was included in 2.6.27.5. I wanted it in 2.6.26-stable too, but that branch seems to have been closed now.

Ah, right, I was looking at 2.6.26.6 and thinking it was 2.6.27.6. :-P
Thanks.

Is that likely to do anything for the old SATA150-TX4 ?
I have 2 of them in a machine and I've been dropping drives under write load recently but it was a 2.6.27.4 kernel.
Reboot required to pick up the drives again (unless the kernel panics and it reboots itself - which it's been doing also).

Does unloading and reloading sata_promise fix the problem? If your root is on promise, you'll need to try this from usb stick or live CD.

Hi Michael and list,

The hardreset fix was included in 2.6.27.5. I wanted it in 2.6.26-stable too, but that branch seems to have been closed now.
Having read about the hardreset fix I have just tried 2.6.27.5 on my setup (which works ok at 1.5Gbps but fails at 3.0Gbps).
I'm still experiencing the same "link is slow to respond" problem using sata_promise in linux-2.6.27.5 with my Promise Technology, Inc. PDC40718 (SATA 300 TX4) (rev 02) and 4 Seagate 500GB ES drives Model: ST3500630NS, Firmware: 3.AEE (with 1.5/3.0Gbps jumper removed = 3.0Gbps)
After doing:
dd if=/dev/sda of=/dev/null bs=1M &
dd if=/dev/sdb of=/dev/null bs=1M &
dd if=/dev/sdc of=/dev/null bs=1M &
dd if=/dev/sdd of=/dev/null bs=1M &
it runs fine for a while, then fails similar to my experiences with earlier kernels.
Best regards,
Peter

Having read about the hardreset fix I have just tried 2.6.27.5 on my setup (which works ok at 1.5Gbps but fails at 3.0Gbps).
Best regards,

Does unloading and reloading sata_promise fix the problem?

Hi Tejun,
Thanks for your reply.

Does unloading and reloading
sata_promisefix the problem?
I had sata_promise linked into the kernel so I had to recompile and reboot. The reboot fixed it (didn't turn power off - just reboot).
I then tried with sata_promise as a module. Four dd's reading the drives and shortly same problem:

then the not-so-nice way using rmmod -f and inserting it again. It doesn't work. Here are the relevant parts from dmesg (removing and inserting):

Hi Tejun,
Thanks for your reply.

Does unloading and reloading
sata_promisefix the problem?I had
sata_promiselinked into the kernel so I had to recompile and reboot. The reboot fixed it (didn't turn power off - just reboot).I then tried with
sata_promiseas a module. Four dd's reading the drives and shortly same problem:[ 700.520101] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x1380000 action 0x6 frozen [ 700.520112] ata1: SError: { 10B8B Dispar BadCRC TrStaTrns } [ 700.520120] ata1.00: cmd c8/00:00:90:0e:e6/00:00:00:00:00/e1 tag 0 dma 131072 in [ 700.520122] res 40/00:28:00:00:00/00:00:00:00:00/40 Emask 0x4 (timeout) [ 700.520126] ata1.00: status: { DRDY } [ 700.520169] ata1: hard resetting link [ 705.910331] ata1: link is slow to respond, please be patient (ready=-19) [ 710.531474] ata1: COMRESET failed (errno=-16) [ 710.531531] ata1: hard resetting link [ 715.920526] ata1: link is slow to respond, please be patient (ready=-19)

I tried removing
sata_promisethe nice way using modprobe:# modprobe -r -f sata_promise FATAL: Module sata_promise is in use.then the not-so-nice way using rmmod -f and inserting it again. It doesn't work. Here are the relevant parts from dmesg (removing and inserting):
Oh... you first need to wait for the kernel to be done with the devices.
ie. unmount all filesystems living on those && wait till EH finishes.

I didn't have any filesystems mounted but learned that the 4 disks
participate in a md raid5 set. To be sure I tried everything again from the beginning (reboot) without enabling md on the four drives. Here are the results:
1. started the four dd processes which ran to completion without any errors. Started them again and this time sda failed as usual.
2. modprobe -r sata_promise - no warnings/errors: removed successfully
3. modprobe sata_promise - only three drives show up
4. modprobe -r sata_promise - no warnings/errors: removed successfully
5. modprobe sata_promise - more channels complain - no drives are found

I tried removing
sata_promisethe nice way using modprobe:# modprobe -r -f sata_promise FATAL: Module sata_promise is in use.Quoted 6 lines
Quoted 3 lines
then the not-so-nice way using rmmod -f and inserting it again. It doesn't work. Here are the relevant parts from dmesg (removing and inserting):
Oh... you first need to wait for the kernel to be done with the devices.
ie. unmount all filesystems living on those && wait till EH finishes.I didn't have any filesystems mounted but learned that the 4 disks participate in a md raid5 set. To be sure I tried everything again from the beginning (reboot) without enabling md on the four drives. Here are the results:
1. started the four dd processes which ran to completion without any errors. Started them again and this time sda failed as usual.
2. modprobe -r
sata_promise- no warnings/errors: removed successfully3. modprobe
sata_promise- only three drives show up4. modprobe -r
sata_promise- no warnings/errors: removed successfully5. modprobe
sata_promise- more channels complain - no drives are founddmesg:

COMRESETs are failing with EBUSY while
ata_sff_check_ready()is returning ENODEV. Hmmm... Does the attached patch change anything?
patching file drivers/ata/sata_promise.c
Hunk #1 succeeded at 707 (offset -2 lines).
Yes, it actually helped. Tested it twice and both times the following happened:
1. started the dd's from all four drives
2. /dev/sda fails after a while as usual
3. two hardresets happen on sda - the second limits the link to 1.5Gbps
4. dd continues without hickups (and when completed normally I started yet another dd test which ran to completion without any errors).
So at first error the hardreset kicks in and saves the day (and downgrades to 1.5Gbps which prevents the problem from happening in my setup).
Thanks a lot!
Best regards,

These hotplug_status things worry me. Hard resets trigger hotplug events, but all recent kernels should disable them in ->freeze. This used to be the case.
Either libata isn't freezing the port before the reset, or ->freeze isn't marking the port properly causing the interrupt handler to interpret (silent) hotplug status bits when it shouldn't, or (horrors) ->freeze isn't working any more.
Stray hotplug events prolong EH handling sequences and can even cause port disabling due to EH failures.

Hello, Mikael.

Tejun, what's the functional difference between the original sata reset method and the one you changed it to?
It means that the controller is having trouble updating the TF registers from the first D2H Reg FIS after hardreset and thus requires a follow-up SRST to get the device signature and initial DRDY status right. This is actually quite common among SATA controllers. Some ahci's and sata_sil24 can't do it either. sata_sil is one of the best behaving ones in this regard. It looks like sata_promise needs follow-up SRST after all. I'll put the header and send this patch to Jeff.

libata definitely is calling ->freeze but some controllers seem to ignore IRQ masking during hardreset. Maybe promise falls in this category too? For those controllers, irq handler should be ready for spurious interrupts during reset. If anything needs to be done differently, it can use ATA_PFLAG_RESETTING to tell whether reset is in progress (see ahci.c for example).

Stray hotplug events prolong EH handling sequences and can even cause port disabling due to EH failures.
libata EH should be smart enough to handle this if the PHY event happens during reset and scheduled reset. EH will clear those actions on successful completion of reset but before verifying the connected devices (spurious events are ignored w/o losing actual device presence).
Thanks.

PATCH 1/1 sata_promise: request follow-up SRST
In reply to Mikael Petterssonsata_promise hardreset doesn't seem to be able to acquire the initial D2H Reg FIS after hardreset leading to hardreset timeouts. Request follow-up SRST.

Peter, can you please test this one too? It's essentially the same code just slightly prettier. Mikael, what do you think about this?

I'm still testing the new patch (on 2.6.27.7), but so far I haven't had any failures - it seems my hardware has started to behave well - very unfortunate ;-)
I'll keep on testing - hopefully I'll see some of the usual errors soon
- and the new patch recovers alright.

Peter, can you please test this one too? It's essentially the same code just slightly prettier. Mikael, what do you think about this?
Does unloading and reloading the driver make the device recognized again?
Thanks.

Yes I tried modprobe -r sata_promise and modprobe sata_promise: It didn't recognize the device. I forgot to post the dmesg output, sorry.

sata_promisehardreset doesn't seem to be able to acquire the initial D2H Reg FIS after hardreset leading to hardreset timeouts. Request follow-up SRST.http://article.gmane.org/gmane.linux.ide/36186
Signed-off-by Tejun Heo <[email protected]>---
Peter, can you please test this one too? It's essentially the same code just slightly prettier. Mikael, what do you think about this?Jeff, please commit only after Peter's verification and Mikael's ACK.

hrm.... at this point we have deviated massively from the standard Promise method of hard reset...
* set PMP port
* make hotplug irqs
* reset port# in PDC_GLOBAL_CTL
* pdc_reset_port()
* reset FPDMA -- probably a good idea even if not doing FPDMA
* clear SATA Error register (0xffffffff)
* clear errors-reported-from-link-layer register
* wait standard length of time for SATA connection
* clear hotplug bits
* set PMP port
The PDC_GLOBAL_CTL bitbang is the most notable missing element in the hard reset path, though we also miss clearing an apparently-important error register as well. FPDMA reset would be a good idea I think, even if not in use, mainly for paranoia's sake and because that's what Promise's driver does.

->freeze() masks hotplug irqs, though it seems the events are still logged and wrongly interpreted by the irq handler.
The other Promise bits should be easy to do, though FPDMA reset will need special-casing for 1st-vs-2nd generation and maybe also sata-vs-pata.
I'll look into it.

hard reset path, though we also miss clearing an apparently-important error register as well. FPDMA reset would be a good idea I think, even if not in use, mainly for paranoia's sake and because that's what Promise's driver does.
Here's a patch on top of 2.6.28-rc6 that should make sata_promise's reset sequences a closer match to what Promise's drivers do.
- soft reset (pdc_reset_port):
* wait for ATA engine to not be in packet command mode (2nd gen only)
* write reset bit in PDC_CTLSTAT before the first read in the loop
* for 2nd gen SATA follow up with FPDMA reset and clearing error status registers
- hard reset (pdc_sata_hardreset):
* wait for ATA engine to not be in packet command mode (2nd gen only)
* reset ATA engine via the PCI control register
* Tejun's change to use non-waiting hardreset + follow-up SRST
I'm not changing the hotplug mask bits since they are taken care of by sata_promise's ->freeze() and ->thaw() operations. And I'm not writing the PMP port # because that's always zero (for now).
Tested here on a SATAII150 TX2plus w/ two sata disks, some hdparm -y
+ smartctl tests which used to cause timeouts on one of those disks, and some parallel dd:s to stress things a little. No issues found. I'll test it on a 1st gen 20378 next week.
Testers welcome.

Here's a patch on top of 2.6.28-rc6 that should make sata_promise's reset sequences a closer match to what Promise's drivers do. ...snip...
Testers welcome.
I don't have physical access to my system at the moment, and some channels/drives had already failed during previous testing. Without a proper power-cycle the system did not recover the failed channels when rebooted into 2.6.28-rc6 with your patch :-(
Best regards,
Peter

hard reset path, though we also miss clearing an apparently-important error register as well. FPDMA reset would be a good idea I think, even if not in use, mainly for paranoia's sake and because that's what Promise's driver does.
Here's a patch on top of 2.6.28-rc6 that should make sata_promise's reset sequences a closer match to what Promise's drivers do.
- soft reset (
pdc_reset_port):
* wait for ATA engine to not be in packet command mode (2nd gen only)
* write reset bit inPDC_CTLSTATbefore the first read in the loop
* for 2nd gen SATA follow up with FPDMA reset and clearing error status registers
- hard reset (pdc_sata_hardreset):
* wait for ATA engine to not be in packet command mode (2nd gen only)
* reset ATA engine via the PCI control register
* Tejun's change to use non-waiting hardreset + follow-up SRSTI'm not changing the hotplug mask bits since they are taken care of by sata_promise's ->freeze() and ->thaw() operations. And I'm not writing the PMP port # because that's always zero (for now).

Tested here on a SATAII150 TX2plus w/ two sata disks, some hdparm -y
+ smartctl tests which used to cause timeouts on one of those disks, and some parallel dd:s to stress things a little. No issues found. I'll test it on a 1st gen 20378 next week.Testers welcome.
Any updates?

Not really. I've kept the patch up to date for newer kernels, but there's been no testing by others that I know of. Do you want to include it in a testing branch?

I can at least make sure it is in #ALL and #NEXT, two meta-branches in libata-dev.git that are forwarded to akpm's -mm tree and linux-next, respectively, for wider public testing.
We can give it more-public testing and hopefully get a bit more feedback.
And you can always post to linux-kernel and linux-ide requesting testers... that's something even non-programmers can do. Something like "Request for SATA Promise testing" would surely get at least a few responses...

I have tested this patch:
http://user.it.uu.se/~mikpe/linux/patches/2.6/OLD/2.6.28/patch-sata_promise-reset-updates-v1-2.6.28
On a vanilla 2.6.28.6 kernel.
It works without any problems.
Unfortunately I had to replace a faulty power supply - which may have been the cause for my system failing earlier (as reported in previous postings to this list).
Hardware:
AMD Barton 2500 on Nforce2 motherboard with
Promise Technology, Inc. PDC40718 (SATA 300 TX4) (rev 02)
4 Seagate 500GB ES drives:
Model Number: ST3500630NS
Firmware Revision: 3.AEE
(with 1.5/3.0Gbps jumper removed = 3.0Gbps)
