I provoked a network related oops as user 'grant', with this CLI input boo-boo on an ssh terminal:
grant@sempro:~$ rm /home/share/config-2.6.17-rc6-mm1a dmesg-2.6.17-rc6-mm1a
/home/share is an NFS mounted directory
Was able to login direct as root and copy the oops info with mouse (gpm) copy/paste, but console locked up on localnet access, here's the guff:

Just done it again, not my finger trouble at all, again via ssh terminal, deleting a file from an NFS mounted directory:
grant@sempro:~$ rm /home/share/dmesg-2.6.17-rc6-mm1a Segmentation fault
Note: the file was successfully deleted. No reboot for this one:

Since I use NFS here, no further testing 33-rc1 on the other boxen. More info, testing on request. The server exporting the NFS share is running 2.4.32-hf-latest:
Now running: 2.4.32-hf32.6 Uptime: 08:19:43 up 16 days, 14:27, 1 user, load average: 0.00, 0.00, 0.00
