While running the following command on a Reiser4 partition mounted on a
MD RAID-0 device on top of two SCSI disks:
find -type f -print0 | xargs -0 cat > /dev/null
I was running this on the local machine, not on the NFS mounts. In
fact, the NFS mounts should have had none, or very little, activity.
I started getting the following error messages. I had been running
2.6.16-rc5-mm3 and hadn't noticed anything like that, so when I get some
time I may try to isolate it, if I can reproduce it.
But, in case anyone else knows the problem, here it is
BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000
