I need some help. My system keeps locking up on me or suddenly rebooting.
Sometimes I'm able to telnet in and shutdown but usually I have to hit
the power button and pray that the disk isn't thrashed. I'm running
RedHat 7 and it happens with the supplied kernel or with a new kernel.
I'm currently running linux-2.4.0-test8 right now and it is compiled
using kgcc. (Found that tip in a message here) I searched through my logs
for help and find lots of these Oops messages. I then did some searching
on what Oops is. I was told to run ksymoops to get more info but this
extra info is way over my head. I'm posting this here in the hopes that
somebody can help me pin down what module or kernel setting is causing
all my problems. Thanks for any help.
