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.
