For about a week, my workstation has been crashing every day or so.
Typically it happens late at night while BackupPC is backing up a hard
drive. With "tail -F /var/log/messages" running I saw EXT3 mentioned a
few days ago and started suspecting a hard drive problem.
Last night it happened again. This time my "tail ..." window was
opened full screen so I saw all the messages and know more. Here's
part of what I wrote down (until I got tired of writing):
BUG unable to handle kernel NULL pointer dereference at 0000008
IP ffffff8027ce14 free_block+0xb4/0x160
PGD 11b638067 PUD 11b631067 PMD 0
Oops 0002[1]SMP
...
Call Trace
8027cac0 cache_flusharray+0x60/0xe0
8027cc46 kmem_cache_free
I'm running a 2.6.25-gentoo-r7
To learn more about what's happening (and to more easily record
all the kernel messages), I'm now running "tail -F /var/log/messages"
from a second machine (via an SSH session).
Questions:
Is there a better way to capture the full BUG output???
Once I have the full BUG output, what's the next useful thing to do?
Thanks!
David
