Comment= # 3 on bug 97500<= /a> from Micael Bergeron 
I also have this behavior on Linux 4.7.2=20
I tried either to unbind on /sys/bus/pci/drivers/amdgpu/unbind or remove the
device and trigger a rescan using /sys/bus/pci/devices/.../remove,
/sys/bus/pci/rescan.

I have kernel panics and/or system hangs either way.
It would be awesome to be able to yield the GPU to a VM then claim it back =
when
finished.
