            Bug ID: 89961
           Summary: System Shutdown on High Load (Radeon)
           Product: Drivers
           Version: 2.5
    Kernel Version: >3.13
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: swoorupj at gmail.com
        Regression: No

Whenever playing any applications that requires high graphics performance
especially games like Left For Dead 2, for a certain period of time, my system
suddenly shutdowns down. It feels like power has been cut off all of a sudden.

I am not sure as to what the cause of the problem exactly is. But it occurs
with radeon module. It does not happen with catalyst, but I can't use catalyst
it has problem with rendering.

One thing I notice is that temperature is very high during this stage. 

Could it be due to a bug in which the frequency clocks are transitioned in the
GPU? Or simply due to overheating? Note that this does not occur with windows
driver.


I have a AMD A6-4400M APU with Radeon HD 7520G]
