[vfio-users] OVMF: Boots only first time after driver installation

[Eddie Yen]

Hmm.... It seems like your R9 285 really got reset issue.
As I known there're few AMD cards can't reset correctly, and most issues is
about VBIOS (as I saw).

If you mean VM reboot, I guess the reason is that VFIO goes reset the
device when shutting down VM, but can't reset (shutdown) correctly in some
reasons.
And reboot works just because rebooting won't "shutdown" the device.
I met this issue long time ago when VFIO released at beginning. And I was
using GTX480 in that time.

I remember that you can compile VFIO as debug mode.
You can find in Archlinux forum [1], but I'm not sure that work or not, it
was 2 years ago message, maybe it no longer work already.
