I configured bbswitch to not set any states automatically...
So it's possible to obtain and verify the GPU power state.
However I removed the bbswitch module and booted with nouveau.
Kernel 4.7.2: nouveau switches the discrete GPU off.
I can't trigger the freeze, because bbswitch is missing.
I'll work with the system and see if it will freeze.
Kernel 4.8-rc4: nouveau does not care about the power state and
the discrete GPU is never switched off. I will notice
this, because the second cooling FAN will stop...
Same log messages as send before.
