FYI: "oss-compat" is installed.

I've finally been able to reducte the number of processes to get a full trace; see attached file.

Please note that in this case the proprietary "nvidia" module was loaded, since I currently onyl have remove access to the machine.
The original trace from yesterday happend without the nvidia module ever being loaded.

Not that I know of: Booting 3.9.9 works fine, 3.10.x shows the problem.

...

I just upgraded from 3.9.9 to 3.10.0; also tried 3.10.1 which did not improve the situation.
