Bug ID: 96243
Summary: GPU initialization fails
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: hiwatari.seiji@gmail.com

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 various
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 able
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
