Title:
  Kernel 3.13-rc7 [AMD Radeon HD 6800] System Crashes and Reboots

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Using the latest 3.13-rc7 on two of my AMD machines, both of which
  have Radeon HD 6850 graphics cards in them, the system crashes when
  playing videos. I think it may be easier to cause the crash when
  playing a video that is 720p+. It also is not limited to crashing when
  playing videos, but can also crash simply from browsing the web or
  doing anything that causes a demand on the GPU. It may or may not be
  related to DPM implemented in the latest kernels. Using kernel 3.12
  from Trusty repos with DPM enabled, it works fine. I have a machine
  with a Radeon HD 7950 but I have not tested it yet. Similarly, I have
  used an AMD Richland APU which crashes with kernel 3.13 immediately on
  the login screen. Put simply, there needs to be a lot of testing of
  AMD chips before releasing kernel 3.13 for Trusty stable.
