Guest (laguest@xxxxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |laguest@xxxxxxxxxxx --- Comment #11 from Luke A. Guest (laguest@xxxxxxxxxxx) --- I can confirm that the OS completely hangs when unbinding R9 380 (Tonga Pro) with X running. Works fine with X off. I have amdgpu and vfio-pci both in kernel, used the following to unbind it. #!/bin/bash for dev in "$@"; do vendor=$(cat /sys/bus/pci/devices/$dev/vendor) device=$(cat /sys/bus/pci/devices/$dev/device) if [ -e /sys/bus/pci/devices/$dev/driver ]; then echo $dev > /sys/bus/pci/devices/$dev/driver/unbind fi echo $vendor $device > /sys/bus/pci/drivers/vfio-pci/new_id done lspci -nnk shows: 03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
