Hi Alex,

thanks alot again! But I'm sorry, bad news...

the debug output is gone now (as expected), but the system behaves equal.
Besides that the garbled screen looks a little different now (lots of little
squares with different colors instead of stripes), I again see a crash in
Xorg.0.log and the above mentioned lockups in dmesg:
