Comment # 30 on bug 109955 from Sam

Update: I can now confirm, at least in my case, that the freezes DO occur using
the parameters above, and also with all of them (shown below), while doing
another test round on Pillars of Eternity.

amdgpu.dc=1 
amdgpu.vm_update_mode=0 
amdgpu.dpm=-1 
amdgpu.ppfeaturemask=0xffffffff 
amdgpu.vm_fault_stop=2 
amdgpu.vm_debug=1 
amdgpu.gpu_recovery=0 

I was continuously writing dmesg to a file but yet again I didn't get any
messages/warnings/errors.
