[Bug 96964] R290X stuck at 100% GPU load / full core clock on non-x86 machines

--- Comment #9 from Timothy Pearson <kb9vqf at pearsoncomputing.net> ---
A bit more information:
 * Disabling DPM does not fix the problem (dpm=0 on module load)
 * Using hard reset instead of soft reset just makes a complete mess / host
hang
 * It looks like only the CP block needs to be reset (GPU softreset: 0x00000008
corresponds to RADEON_RESET_CP).
 * After reset DPM is broken, but DPM also breaks after unloading / reloading
the radeon module so this may be a red herring.
