--- Comment #23 from Alex Deucher ---
Sorry, I should have been more clear, on kernel 3.12, does the dGPU switch on
again properly after via debugfs after you've disabled it via debugfs? The
problem you are sseing is that the GPU turns off ok, but seems to have problems
turning back on:
[ 52.340438] radeon 0000:01:00.0: Refused to change power state, currently in
D3
[ 52.416464] radeon 0000:01:00.0: Refused to change power state, currently in
D3
[ 52.432469] radeon 0000:01:00.0: Refused to change power state, currently in
D3
and the registers are all reading back 0xffffffff which usually means the
device is still powered off.
Also why are you using radeon.no_wb=1? That may cause problems.
