Subject: Kernel BUG 2.6.33-rc2 


I just seem to be hitting this bug since I upgraded to Slack 13 and started 
using EXT4 yesterday. The file copy is between 2 EXT4 filesytems. I can 
trigger this bug pretty reliable. After the bug occurs, systems seems to be 
unusable and needs a reboot.

my .config can be found at http://www.bencastricum.nl/.config (when the 
system hasn't crashed)

I appreciate any suggestions.

Ben
