--- Comment #30 from rafael castillo jrch2k10@gmail.com --- ok i tried the latest patches in drm-fixes and the crashes seemed to stop but i can't get the gpu to reclock
i tried /sys/class/drm/card0/device/power_dpm_state to performance alone and it never scales from state 0
if i try to force it with /sys/class/drm/card0/device/power_dpm_force_performance_level only accepts low
auto or high returns bash: echo: write error: Invalid argument
