Hey VFIO-Users and supporters,
since april I am a happy user of vfio and graphics card redirection to
Windows 10 Pro. Since the last updates I got some trouble with my setup,
that the windows vm is crashing if there is a driver and the RX 580 is
passtroughed to it.
For troubleshooting purposes I installed a fresh new Windows 8.1 Pro
machine, there the driver cant get installed because the driver setup
seems to find the wrong pci ven / pci device numbers.
The RX580 is also only detected as a "Microsoft Basic Graphics Adapter".
My old setup which was working fine for months look like this in xml and
is generated from libvirt-manager:

(Dont be suprised, I also tried to passtrough both pci devices -> audio
and graphics, same issue).
Just sayin that I couldnt find any errors or syslog entrys in the logs.
My vfio setup seems also to be fine:
(dmesg | grep vfio)
Command line: BOOT_IMAGE=/vmlinuz-4.10.0-26-generic

The funny thing is, the audio device is correctly detected from the
driver. I also opened a thread on the vfio-subreddit and got redirected
to you guys.
Any help is highly appreciated.
