Bug ID: 98901 Summary: amdgpu doesn't reinitialize after reboot in Xen PV DomU 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: msgctl@centzontotochtin.org
Created attachment 128264 --> https://bugs.freedesktop.org/attachment.cgi?id=128264&action=edit Logs from Xen Dom0 and affected DomU
I'm not sure whether this is a Xen or amdgpu bug.
amdgpu consistently does not reinitialize after paravirtualized Xen DomU reboots. It's a PCI passthrough setup - the physical machine does not reboot and it can't reset PCI Express devices.
This setup is working fine until I need to reboot the affected DomU.
DomU: Debian testing (29-11-2016) Linux version 4.7.0-1-amd64
Dom0: Debian GNU/Linux 8.6 (jessie) Linux 3.16.0-4-amd64
Graphics adapter: Radeon RX480
I attached an archive with all the relevant logs I could gather. Please contact me for further information/testing.

Can you try a more recent kernel? 4.8 or 4.9?
I added a DomU startup log from a 4.9 series kernel. The result is the same in 4.8.
