Greetings,
I'm facing a dpm regression in 3.14 on my radeon TURKS (pci id 1002:6840).
Upon loading the radeon module with dpm enabled, the screen goes black and the
computer locks up.
The problem first appeared at 6c7bccea390853bdec5b76fe31fc50f3b36f75d5
drm/radeon/pm: move pm handling into the asic specific code
and is still present in 3.15-rc1.
Loading the radeon module with dpm disabled works.
I captured the relevant kernel messages using a netconsole (attached); there
is an oops in radeon_ring_write presumibly during the test of ring #5.
Thanks,
Giancarlo
