Hi.
I get an oops reproducably with 2.2.17 and 2.2.18pre21 on a stock RH 6.2
system. I cannot trigger it with the RH supplied kernel (2.2.14-5.0).
I also got it with 2.2.17pre10 which prompted me to upgrade the kernel.
I initially suspected bad RAM but have exchanged the RAM with memtest86'ed
RAM for no improvement.
What I do: I try to back the system up with tar zcvf /var/backup.tar.gz
-X exclude /lib /sbin /var /bin /etc /boot /home /root /usr
(the exclude file contains the path of the file itself, i.e.,
/var/ backup.tar.gz).
Running 2.2.17 I got the following oops during the backup, i.e., tar
had not finished yet (the exact place in the backup process varies):
ksymoops 0.7c on i586 2.2.17. Options used

-k /proc/ksyms (default)

Which compiler are you using?

Exclude /dev and /proc also, /lost+found if you have it, and /mnt if you
only want that drive. Perhaps things like /proc/kcore make trouble...
