Michael heimpold, thank you for providing information on prior Ubuntu releases, a WORKAROUND.
Could you please undo all WORKAROUNDs, and test mainline kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc1-quantal/ following https://wiki.ubuntu.com/Kernel/MainlineBuilds ? ** Description changed: I do not have any szenario howto reproduce this bug immediately. currently it occurs after a few minutes of working, or somethings after a few hours. Please advice howto debug further.
