Bug ID: 97500 Summary: Cannot unbind GPU from AMDGPU Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: commendsarnex@gmail.com

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
