No more pass through after upgrading from 6.9.2 to 6.11.5

[Jessie]

Can anyone help. I have a machine with what was essentially the unraid appliance a few years ago. ie xeon e3 and the 14 sata port supermicro motherboard and a radeon graphics card. It is still working fine on version 6.9.2. (I'm on it now)  If I upgrade to 6.11.5, no more passed through graphics.

 

Any ideas?  Or am I destined to be on 6.9.2 forever?

same here. GPU passthrough not working anymore since 6.10.

Same for Windows 10 and LibreELEC

 

tried everything I could find including:

- removing GPU Bios

- tried with and without multifunction device

- add 'video=efifb:off' to the append of my syslinux config

- tried allowing unsafe interrupts

- trying different Q35 versions

- creating new vm from scratch

 

this is what my LibreELEC vm shows in the log when trying to boot:

I solved my problem switching to Intel IGD passthrough.

I made a writeup here. maybe this can help you aswell:
