REMOVED FOR NOW

- RMAP

REMOVED FOR GOOD

- LLC (See 2.5)
- VaryIO (Never accepted mainstream)

Considering you seem to have revived 2.4-ac, would you be interested in collecting various bugixes wrt cli/save_flags/restore_flags or is that better off in 2.5? (or maybe it doesn't even really matter?)

Yes, Debian still has an old compiler

	gcc version 2.95.4 20011002 (Debian prerelease)

and my reported problems should simply show the difficulties it encounters.

So what is the proper workaround for this specific compiler bug? I guess "args..." requires at least one arg or it errors.

Yes, thanks, I can confirm that this patch fixes the compilation problem.

I had some strange bug using 2.4.21pre3-ac2 :
at rebooting after a freeze (my machine freezes from time to time whatever the kernel is, I'm still diging that point) fsck.ext2 was not able to finish checking my /home (59Gb), it systematically got a signal 11 (I tried several times).

rebooting using my previous kernel (2.4.20 with a minor patch for the i845G AGP mess-up) was enough so that the fsck worked fine at the first attempt with this kernel.

this triggers two questions :
o is the new piix-ide faulty ?
o are 256 Mb of memory enough for fscking a 58Gb partition ?

about signal 11, I tested my machine with several concurent kernel built with no signal 11 before (with 2.4.20 and prior)

the machine is an ASUS P4PE motherboard, 2,4GHz PIV 256Mb and a nvidia Ge4-Ti4200. (at signal 11, the nvidia tainted module was not loaded yet :)

thanks in advance for any enlightment...

here-below, the lspci and /proc/pci...

If its freezing with old kernels I'm somewhat less interested

Not from reports I have except for two reports about MWDMA (old non UDMA) which appear to be a chipset errata I need to deal with

There are several possibilities, but I would suspect you have memory which is just marginal, and with some combination of access patterns you trigger a sig 11 problem. I have the same board, with 72 bit ECC capable memory, and I'm running all of the BIOS speed options (section 4.4 of the manual) set at default, rather than tuning for any extra bit of performance.

If you have pushed any of the CPU or memory speeds, obviously that's a place to return to default, but I suspect what you have is marginal memory. Best is to borrow a stick and run on other memory, 2nd best is to slow the speeds a bit and see if that works better.

Clearly this is only an educated guess.

Doing interesting things with little computers since 1979.

I'm seeing enough other -ac specific errors to be fairly sure its not just hardware in the current -ac tree case. I don't know what the common factor is yet - it 'works for me' which makes it hard to pin down

Guess #1 is reverting mm/shmem.c. Guess #2 is reverting the buffer cache changes. Guess #3 is new IDE + highmem and Guess #4 is quota related (are people seeing the problem with quota disabled ?)

I'm now running -ac3 and it seems more stable. I've got a Dual Xeon 550 Mhz Dell with 768mb of ECC memory and a Matrox G450 card. Nice stable system usually.

I'm not running with quotas at all, and I've seen the complete lockup under -ac1 and -ac2. I'll see about stressing -ac3 with some filesystem stuff to see what happens.

2.4.21-pre3-ac4. I've got a Toshiba Satellite 1800 here. P3 mobile (Coppermine)/1100, 256MiB RAM, no higmem or other stuff, RH 8.0 + updates. Quotas are enabled. USB mouse, CD player running (yep, sound works now). When trying to update (rpm -Fhv) rpm segfaulted, later X went dead. alt-F1 gave me a console (upper half of screen, dark green letters, microscopic font ;-). Rebooted fine tho.

* Alan Cox <[email protected]>:

I got an oops with that kernel on two different machines:

ksymoops 2.4.8 on i686 2.4.21-pre3-ac2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-pre3-ac2/ (default) -m /boot/System.map-2.4.21-pre3-ac2 (default)

Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.

Why you can't find your system administrators:
(S)he's catching twenty winks under the floorboards, tread gingerly. 

Can you build the kernel with the patch to mm/shmem.c reverted and see if that fixes your crash ?

* Alan Cox <[email protected]>:

Well, yes. Should I remove all changes to "mm/shmem.c" that are done from the ac2 patch?

Okay, so I have this coworker who believes that NT is God's Gift to Sysadmins. 
There are lots of weird gods around, aren't they? 
Yeah, he means Cthulu. That's the kind of OS he/she/it'd give as a gift. 

* Ralf Hildebrandt <[email protected]>:

Not really. I rebooted and then the ac2 crashed DURING a fsck that was caused by reaching the maximum mount count.
I'm outta here and back to 2.4.21pre3 :)

Curious indeed. I guess we'll find the problem when I submit the troublesome change to Marcelo 8). I'll look at that keyboard fix, that seems a fairly sane workaround. Next stop is zapping the other bits of journal related stuff and checking network card fixup corner cases - what ethernet do you have btw ?

It's mathematical: (uNsTable - NT) = usable.

siolx_cleanup in drivers/char/cd1865/cd1865.c is __exit but called from the __init function siolx_init causing a .text.exit error when compiling this driver statically into the kernel. The following patch that removes the __exit fixes it:
