Subject: [OOPS] nfs, similar to raid5 bug reports


This from attempting to read a nfs mounted directory. ext2 in this case,
also had one with isofs over nfs.

This looks suspiciously like Jasper Spaans' current report on raid5.


Unable to handle kernel NULL pointer dereference at virtual address 0000003c
