I have a server that is* and/or crashing quite regularly. It has
a Supermicro p4dc6 motherboard with dual Xeon 1.7G processors. I am
using the onboard scsi with two 36G IBM drives and the onboard ethernet
eepro100. I have it running Redhat 7.3 with the 2-4-18-19.7.xsmp kernel.
The BIOS is version 1.0.
The last time it crashed it gave an Oops 0002 which I copied down from
the screen. I ran that through ksymoops, but I do not really know what I
am looking for. I have attached both the Oops text and the ksymoops
output to this message. Can anyone tell from this what is going on? I
need to get this machine stablized before it can go into production. I
cannot tell if I have a software or a hardware problem.
Any help is greatly appreciated.
Thanks, Barry

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.
