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 con=
tact
me for further information/testing.
