Random Kernel Oops

[Johannes Matjeschk]

Hello Linux-Kernel Team,

I'm getting randomly kernel Oops Messages. It started first when I
tried to copy a harddisk to an image with the program safecopy 1.7.
Since then it randomly appears.

== What I've done already ==
* Tested every Hardware. I'm PC Technican for a small IT Firm, so I've
the possibility to test and change every Hardware. I've switched the
mainboard, RAM, NICs and Harddisk (from SSD to SATA).
* I've re-installed the system many times.
