Hi guys. With AMDGPU, if I try to unbind my GPU from amdgpu, I get a hard
kernel lockup. My GPU is the RX 480. I'm currently on 4.7.2, but I've tried
drm-next-4.9 also. I've tried both echo $CARD_PCI_LOCATION > unbind, and
unbinding the vtcon and then modprobe -r amdgpu. When I had my HD 7950, the
echo $CARD_PCI_LOCATION > unbind method worked every time. I'm not sure how to
get any debug info, since even an ssh session locks up. I tried using pstore,
but no logs were saved.
Please let me know if you have any ideas or need any more info.
Thanks,
Sarnex</pre>
