Hi Sami.

thank you for your answer.

As of today the crash is gone on my x86_64 system (all testing repos
enabled). I guess you tried on x86_64, but not i686? Don't know why
its gone in x86_64, but anyway, i686 still crashes. And the headless
server I use powertop on to elegantly optimize power settings still
crashes when using powertop --auto-tune. The funny thing is that the
settings get optimized nevertheless as a call of powertop wihout
- --auto-tune parameter shows me.

I tried this but there was no useful output due to missing debugging
symbols, I guess what do I have to do to enable those?

Thank you
