https://bugzilla.kernel.org/show_bug.cgi?id=51381 --- Comment #23 from Alex Deucher <alexdeucher@xxxxxxxxx> --- 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. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
