This is a re-post of my earlier message (Subject: Kernel Oops, unknown
area, NULL pointer dereference) in the standard format.
Apologies for additional traffic.
[1.] One line summary of the problem:
Frequent 2.2.14 kernel oopses, usually w/ eventual crash
[2.] Full description of the problem/report:
Kernel oopses, generally followed by system crash within several
hours (varies, usually 1-12). Persisting since mid-January (several
system changes then, not sure which, if any, triggered this), with
typical intervals being 3-14 days between crashes. Application listed
is often rxvt, but has varied.
I've suspected hardware most of the way through this, system has
been completely swapped, excepting one IDE HD, keyboard, mouse,
and monitor, from the original system.
Crash can happen while system is attended or not. Often happens
while idle (overnight). Occasionally seems to be linked to cron
script activity.
I've run mem tests on old memory (found a fault but couldn't duplicate
it on another system). Stress tested system two nights ago with
simultaneous looping memory test and kernel builds with "make -j3"
option. This ran for ~12 hours w/o problems. Following day, an
idle system crashed.
Speculation has also been that the compiler version may be a
problem.
[3.] Keywords (i.e., modules, networking, kernel):
kernel 2.2.14 gcc 2.95.2 debian woody crash oops
[4.] Kernel version (from /proc/version):
Linux version 2.2.14 (root@angel) (gcc version 2.95.2 20000220
(Debian GNU/Linux)) #3 Thu Mar 2 22:30:22 PST 2000
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
ksymoops 2.3.4 on i686 2.2.14. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.14/ (default)
-m /boot/System.map-2.2.14 (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.
