This is a known issue but we don't know yet what is triggering it. Some problems with the same panic message and the same driver have already been solved. It seems there are remaining bugs which lead to the same symptom but it is unclear why. If there was a known way to trigger the crash on demand it would be much easier to fix the issue. Can you find one? Thanks, Stefan
