dmesg output after modprobing amdgpu

Setup:
QEMU + VFIO running VM with Ubuntu 16.04 and the latest amdgpu driver
(amdgpu-pro 16.20.3)

If the system is started normally, the kernel crashes during boot with vari=
ous
errors (varies from boot to boot!).

If the module (amdgpu) is blacklisted during boot (grub.cfg) and modprobed
afterwards the error always the same [see attached file]:

sw_init 5 failed -12
amdgpu_init failed
memory type 2 has not been initialized
amdgpu probe failed with error -12

Experiments:

- Using the amdgpu version shipped with Ubuntu 16.04, booting works ONCE.
Rebooting/Shutting-Down the VM leads to consecutive errors of not beeing ab=
le
to init the GPU again, probably due to Bonaire PCI-Reset issues. Restarting=
 the
Host itself allows booting the VM once more. Hereafter: Same error.

- A Windows 10 VM does not suffer from those issues. Rebooting/Shutting-Down
this VM works without issues / host-reboot
