Oops with 2.4.17 + NFS patches

Oops with 2.4.17 + NFS patches

Hello lkml people,

The following is the output of an oops that occurred on an AMD Athlon XP
running kernel 2.4.17 with all the 2.4.17 NFS patches applied (from
http://nfs.sf.net/).  The kernel is optimised for P3(Cu).

Something which may be quite important is that we are seeing some quite
random behavior with this machine, it will be fine for a good few hours
then we will get random processes being killed with SIGSEGV / SIGBUS.
All RAM has been replaced in the machine, and we have changed kernels from
2.4.18 to 2.4.17, both show the same behavior.

Any information would be most appreciated!

Kind Regards,

David
