SubjectHELP: 6 JAN 2000 Kernel OOPS running under 2.2.14 now
Date
Alan:

Tried the 2.2.14 kernel here with the same options making is as 2.2.
and unfortunately am still getting oops. this one occurred when the
system was literally doing nothing (I was watching the
/var/log/messages with tail as it happened). Couldn't get a dmesg
output as when I tried that it froze the box. Heres the oops and the
ksym output though.

This is getting very discouraging, do you have any suggestions of how
I can get this system stable again?

George
