I am having a recurring problem with one of my boxes. The box will run
fine from a couple of hours to days and will crash without leaving a
trace of what happened. It is configured with a serial console and I
managed to get a kernel panic from it and have included the ksymoops
output below. The box is running SMP with 2 Intel Pentium III/500
processors. We have replaced every piece of hardware in this box and it
does not fix the problem. The drive is running off the Adaptec SCSI
controller built on the board. There is currently only one drive in
this system. The output from ksymoops seems to elude to a problem with
the aic7xxx module but i'm not a kernel hacker so i'm not sure if this
is where the real problem lies. I have also attached the output from
/proc/scsi/aic7xxx/0 for the SCSI controller information. Any help
would be appreciated appreciated.
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 /usr/src/linux/System.map (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.
