Public bug reported:
Kernel panic is occured when I copy big files (over 1GB each) and browsing with
firefox4 at the same time.
System, source and destination HDD are encrypted with Luks AES-XTS.
I encountered this panic a number of times in the same situation.
But I have NOT encountered this panic when I don't use GUI.
(ex: ssh to this machine and copy big files on gnu screen and detach a session.)
Error messages are below.
It may contain some mistake because I input it manually.
