21rc6 serverworks IDE blows even more than is usual :)

Hi Alan, Bartolomiej, Marcelo,

I can't seem to get the onboard Serverworks CSB5 IDE controller (rev 93) in a Compaq Proliant ML350 G3 to work (reliably/at all) no matter what kernel I use:

o 2.4.21-rc6
intrerrupt timeouts, can't r/w from/to drive reliably in pio, dma hosed

o 2.4.21-rc2-ac3
r/w in pio ok, dma hosed

o 2.4.20
intrerrupt timeouts, can't r/w from/to drive reliably in pio, dma hosed

o 2.4.20-pre8-ac3 (has always worked on OSB4 beasts for me) intrerrupt timeouts, can't r/w from/to drive reliably in pio, dma hosed

lspci & .config excerpts plus other bits of info follow. The box is SMP + highmem.

The driver basically hasnt changed throughout these. Are you sure you don't just have a bust Proliant - anyone else runnign 2.4.21-rc on a proliant ?

Hi Alan,

I tried it, works w/o problems for that case.

ciao, Marc

What HW?
What chipset revision?

Tomas Szepe <[email protected]>

No, I can't be sure.

Basically I posted the report just in case somebody finds it useful, for production use I'm sticking in an add-on cmd64x-based controller.

Thanks, Alan.

Tomas Szepe <[email protected]>

Whoa, guess what -- 2.4.21-rc5-ac1 doesn't see the drive at all.

Tomas Szepe <[email protected]>

Well if it helps at all I can vouch for the brokeness on the Proliant ML530. Granted this is not with a 2.4.21-rc kernel but a RedHat kernel 2.4.20-13.9smp. Luckily I don't use IDE drives in this system but it did force me to do a network install since the CDROM is now unusable. Here is the error out of dmesg:

This matches my dmesg line-by-line except for the CDROM model of course. ;)

We're using IDE drives for backups -- mostly because it's not even conceivable to get large SCSI disks for a decent price.

Tomas Szepe <[email protected]>

That may be a different bug with drive tuning in pio mode.

Hi Tomas,

This problem *may* actually be in the hardware... IIRC the CSB5 rev 93h is the A2.1 version of the chip which had big problems with DMA. The workaround options included a messy rework of the PCB or forcing it into PIO mode, so we decided instead to just stick with the A2.0 revision. :)

However all of my knowledge about this particular issue is based on >1yr old information, so if you want to send the output of "lspci -xxx" for pci devices 00:0f.0 and 00:0f.1 I will check them over for any obvious settings the BIOS may have missed.

Its interesting to me.. It probably means my original diagnosis that this was a bad chip revision is unfounded and maybe it can be fixed with the right settings. Could I get an lspci -xxx for devices 00:0f.0 and 00:0f.1 from your box as well so I can cross-ref it with the broken ones?

Duncan, your assumption is quite correct. I got the thing working.

Don't even ask. "/sbin/hdparm -X69 -d1" was the formula.

Oh well.

Just in case this should be needed:

lspci -xxx
