I have an unstable NFS server which tends to reboot every three days.
My current kernel is 2.2.13pre11, which knfsd-1.4.7 (+patches applied).
My configuration is a Dell PowerEdge 4300, Onboard aic7890, DTP raid card,
Adaptec UW2940 (for
managing a DLT tape drive), 2 CPUs, 1 Raid 5 volume of ~80Go.
I am running Redhat 6.0 + latest updates.
Here is the output of the OOPS (taken by hand, since it did not appears in
the /var/log/messages).

I have been unable to run ksymoops :
ksymoops 0.7c on i686 2.2.13pre11. Options used
-v /usr/src/linux/vmlinux (specified)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.13pre11/ (default)
-m /usr/src/linux/System.map (default)
No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?

All the drivers are built in the kernel, not as modules.
Can someone help me ? Is someone can give me a hint on how to run ksymoops
since I do not have yet
a useful output.
Below is some additionnal info.
Thanks for any help. Didier.
