dmesg: boot then unbind

I am getting a kernel panic with Linux 4.8.0 when I unbind my RX480 (XFX Radeon
RX 480 GTR Black 8GB, if that helps) from amdgpu. The system freezes
immediately and only pushes this to the serial console (which is why it is not
in the attached dmesg):

[   80.266963] {1}[Hardware Error]: event severity: fatal

[   80.266967] Kernel panic - not syncing: Fatal hardware error!
[   80.705884] Kernel Offset: disabled

Is this the same issue?

I have attached the kernel output from boot until I got the panic after
unbinding with this command:
echo 0000:01:00.0 > /sys/bus/pci/drivers/amdgpu/unbind

Is there any further information that I can provide to address this issue?
