2) pciehp decides to yank the GPU driver while it's doing a PCI reset (!)
3) When the GPU is reset, it's in a non-finished startup state.
This all happened when I tried to play Second Life with the Radeon GPU as
offload renderer on the Intel GM45 GPU which is doing the display.
To run Second Life I'm using:
$ LIBGL_DRI3_DISABLE=1
$ xrandr --setprovideroffloadsink 0x55 0xa2
$DRI_PRIME=1 ./singularity >& /dev/null &
Here is the Xrandr providers list:
Providers: number : 3
Provider 0: id: 0xa2 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs:
3 outputs: 4 associated providers: 2 name:Intel
Provider 1: id: 0x55 cap: 0xf, Source Output, Sink Output, Source Offload, Sink
Offload crtcs: 2 outputs: 4 associated providers: 2 name:radeon
Provider 2: id: 0x55 cap: 0xf, Source Output, Sink Output, Source Offload, Sink
Offload crtcs: 2 outputs: 4 associated providers: 2 name:radeon</pre>
