kernel panic every few minutes

Upon starting my machine and logging in…I seem to get a KP afer a few
minutes of use. This problem started yesterday evening. I’m not doing
anything special to cause the problem, however, I think it may be linked
to either NetworkManager or the iwlagn driver. Any and all help would be
appreciated and please let me know if you need more information.

Distro:
OpenSuSE 11.1 x86_64

Computer:
HP Pavilion DV9500t CTO
Intel Core 2 Duo T7500 @ 2.2 GHz
2 GB RAM
Intel 4965 WLAN chip

Highly recommended: Backup all your files immediatly if you don’t have
an actual one! I had three times that problem and it was three times a
problem with my hard disk.

What does /var/log/messages say?

hth

As the previous poster said: back up! I’ve had this happen with a bad
sector on the hard drive.

Use a “live” CD to do the backup to a flash drive, if you can. That’s
what I’d recommend.

Curiosity: does it complete booting? Do you get to a desktop before the
panic? Or does it seem to crash at the same point each time? If the
latter, that’s another strong indicator that it’s the hard drive (in
fact, be prepared to get an error when you start the backup; you may
lose some files).

Otherwise, the “live” CD makes another nice test: if you get the panics
at seeming random, you may have a hardware problem. Check for a loose
cable or a RAM stick that needs to be popped back into place more
firmly.

I’ve rmmod’d iwlagn as well as the vmware modules (vmmon and vmci) and
the machine’s been running for 6+ hrs.

EDIT:
Now running on iwlagn, will report back on status in 8 hours.

It completes booting every time and a LiveCD test run with Kubuntu
presents no issues while attempting to do the same internet activities
(browsing youtube & chat, etc…) However, when it may panic is
entirely up to how much internet activity I give my computer. Running on
iwlagn for the past 3 hours or so seems to have panicked my kernel once
again.

Huh. I wonder if the network driver is the issue?

The thing is…it just started happening randomly. So that’s why I’m
wondering what the issue is.

I assume that you’ve already run an fsck? I’m back to the theory that
some part of that hard drive is corrupted. You may have developed some
bad sectors since the install.

The clue is that it doesn’t seem to do it on the live CD (if I’m
reading you correctly). Maybe the live CD isn’t touching the bad part of
the drive.

Here’s a great description for checking a drive thoroughly: ‘Jon
Grant’s Technorama: Check (fsck) your GNU-Linux filesystems! (ext2/ext3
& FAT)’ (http://jguk.org/2007/11/check-your-filesystems.html). Other
articles online will suggest that you try to download a check utility
from your hard drive manufacturer’s Website.

And by the way … speaking from hard experience … if you find more
than a few bad sectors, it’s time to replace that hard drive. It’s dying
and just hasn’t had the good grace to lay down yet. :slight_smile:

Well, I had left my machine on the kernel messages console after I
modprobe’d iwlagn again. There was a stack trace just as I had expected.
Further research during the day revealed that a fix had been implemented
since before the 11.1 release of OpenSuSE. The fix included a new
version of the iwl uCode, which I am running right now without any
issues for the past 4+ hrs. I discarded the HDD theory since SMART
revealed no problems and I’ve always been told by SMART of a failing
drive ahead of time :). The bugzilla page for this bug can be found
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1703.

Hah!! Glad you solved it! So it WASN’T the hard drive. :slight_smile:

Stuff like that can be a booger to run down … … …

Yeah, I ruled out the hdd almost instantly because it didn’t panic at
the same place every time. Thanks to everyone for their help, though :slight_smile:
