system freezing after upgrade from 2.6.22 to 2.6.23 kernel

blabj · 2007-12-11 14:46:36

Upgraded from 2.6.22.9-1 kernel to 2.6.23.8-1 a few days ago.. after about 24 hours of the system being pretty much idle, it froze up. Let me explain.. Its a headless system - no X11 on :0 - I could switch virtual consoles, but each console itself was completely unresponsive. I could ping the system from another host, but an ssh attempt would timeout - the only thing I could do was a hard reboot.

After rebooting, I checked all log files.. nothing.. not a hint of a problem.

Yesterday, I upgraded to 2.6.23.9-1 .. and this morning same thing.. frozen. Again, examining log files reveals nothing.

So - ok, now I'm thinking there is some faulty memory in the system.. booted sysrescd and performed memory test,, passed all tests.. zero errors.

System is P4 3.0GHz w/1 GB ram + 160GB sata drive.. and was running 2.6.22 kernel fine for months.

Any ideas how to debug this problem?

hmm, wonder if we are having similar problems

although i could not tell you if mine happened with kernel update

Except that this is not just a laggy/slow system.. its completely unresponsive except for switching virtual consoles.. which is weird.. if only I could run top!

gazj · 2007-12-11 15:14:41

my system is completely unresponsive if i start using files on the disk in question.

Hence it has taken several hours just to copy 100mb to the other disk.

I am at a complete loss.

I just wondered if your problems were the same then it most likely wasn't my hardware which i suspect.

How about starting your server from the arch install cd, editing rc.conf and stop all non essential daemons starting.

If it is one of them causing problems at least you will get your system started, then turn them on one by one until it hangs again

If I reboot, my system is fine... completely normal.. its only the next day that I find it frozen.. I'm thinking my problem is somehow related to power management.. perhaps its trying to sleep something and locking up..

For you - if you boot a rescue cd (www.sysresccd.org) and mount/access your disks, how do they behave?

gazj · 2007-12-11 15:32:35

will definitely give that a try, if it is ok from a different kernel, then i think i will build a 2.6.22 kernel to fallback on and run it alongside the one in arch core.

Maybe it's worth you trying going back to 2.6.22 if your problems only showed up in 2.6.23.

I think i might just wait for my file copying to finish first, i don't want to lose any work.

Good Luck

try to compile a kernel
try the zen-git
very very fast
maybe it will solve ur problem
give it a try

blabj · 2007-12-12 16:07:14

I compiled/installed the kernel26vanilla from the AUR - still freezing..

Looks like I'll have to revert to 2.6.22 kernel..

I'm also getting this behaviour, on the latest kernel. A month or two ago things were fine.

Relevant Hardware
Abit IC7-G
2x WD Raptors (mk.I) connected on the onboard Sil 3112 chipset
*** 1x 320G Maxtor connected on the the Intel ICH5 (sata_piix module)

Raptor1 (sda) has following partitions: /boot, /home & /root,
Raptor2 (sdb) is a dedicated virtualbox drive
Maxtor is a data drive, with photos & mp3 etc

I've tried plugging the maxtor into a new pci sata controller (Also sil based) and am still getting the same weird behaviour.

The problems as I see it are:
Slow copy operations from any drive to the Maxtor
Slow seek operations (i.e. when watching a movie)
Slow directory listing operations

Is this enough to raise a bug do you think?

tallal · 2007-12-13 11:24:14

Forgot to add, booting from the latest ubuntu live disk and performing the same copy operations resulted in no slowdowns whatsoever.

In fact goggling for "2.6.23 sata slow" throws up a lot of results.

One or two similar experiences:

Perhaps the change is related to the new kernel io scheduler. Try booting with the kernel parameter elevator=deadline.

tallal · 2007-12-13 14:13:51

Hmm thanks that sounds like an option. Will have to try it out when I get home tonight. Weird that it isn't causing more noise.

blabj · 2007-12-14 13:37:36

FYI - I downgraded to 2.6.22-9 kernel (and modules) [which I had previous to upgrade] and I have no more freezing problems. Whether my particular problem was related to SATA or no - it was definitely linked to *something* in 2.6.23.
