Re: gnome-shell stuck because of amdgpu driver [5.3 RC5]

["Koenig, Christian" <Christian.Koenig@amd.com>]

I agree with Daniels analysis.

It looks like the problem is simply that PM turns of a block before all 
work is done on that block.

Have you opened a bug report yet? If not then that would certainly help 
cause it is really hard to extract all necessary information from that 
mail thread.

Regards,
Christian.
