Since the Kernel 3.9.*(don't remember the last number of the version; maybe all of them) i get rare lockups of the radeon  driver. The probability of a lockup is higher the more load on a graphic card. But this is not necessary. This time the driver hung while watching a video in SMPlayer. 

I can't reproduce the bug on purpose, it just happens from time to time, resulting in switched off monitors. Sometimes the kernel is trying to restore the driver but this never happens, resulting in endless switching on and off the monitors. 

Hardware:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde PRO [Radeon HD 7750/8740 / R7 250E]


Thanks!
