I tried that, the logfile only contains "Unable to load --".

The reason is probably, that 767944.cbc ist not a valid filename here.

Please find a list of the files in /tmp as attachment 1.

"x86info -a > /root/2011-01-12_x86info.output"  gave the following error message on the console: "/dev/cpu/0/msr: No such file or directory"

Please find x86info.output attached too.
