Wanted to close the loop on this.  I *think* this issue has been fully resolved with the release of UnRaid 6.9.0, since they are using the Linux Kernel 5.10.x branch: https://wiki.unraid.net/Unraid_OS_6.9.0

 

The original Linux Kernel fix for the AMD 3xxx/Xen CPUs was implemented in 5.8.x, so we should be good now:  https://github.com/torvalds/linux/commit/39a1af76195086349c4302f01e498a5fcbcb11d6

 

I have not yet tried it, but I will when I have potentially a few days to feel the frustration if I have to revert. 

 

I updated my Asus ROG STRIX X370-F bios that previously had this issue and forced me to run a bios from 2018.  Win10 VM with gpu passthrough running issue free on 6.9.1.

THANK YOU THANK YOU THANK YOU FOR THIS THREAD. 

I'm about to convert my ryzen 7 1700, Asus strix x370-f build over to an unraid setup, and I have the option of running an asus strix 1070 (for a W10 passthrough) and a gt710 for unraid. Has anyone tried any other bios(es?) other than 4207 (i.e. 5009) for passthrough, and do they work? 

I have an asus rog strix x370-F gaming, ryzen 5 2600X running with bios 4009. I have a 1060 passed through to a win10 VM. Higher bios versions i tried break the pass through for me.

I also wanted to say thank you for this thread.

I  just built a Ryzen 5 2600X with an Asus ROG STRIX X370-F setup. Wasted a few hours defeated by the stuck in D3 issue. I rolled back the bios to an early version (4009) and windows VM works with GPU passthrough (gtx 1060).
