The System is locking up, not even magic keys work only hard reset. Not often maybe 2 times a week. 

Screen blackens for a second than gets back again but everything is frozen.

I NEVER do Resume or Hibernation or Standby. So this happens occasionally. 

If you search can find some others who have the same problem starting with 3.17

If this is a regression, can you bisect?  Also what version of mesa are you using?  You might try a newer version of mesa.
Comment 3 Andre 2015-01-05 13:31:48 UTC 
Currently using mesa 10.2.8

Will try to install mesa 10.3.5-r1 now.

The error didn't occur since writing this bug. So it's not very often but i will try.
