Re: [Xen-devel] Debugging Windows HVM crashes on Ryzen 3xxx series CPUs.

[Steven Haigh <netwiz@xxxxxxxxx>]

Just to make things annoying, I also get the following message in the 
logs for correctly operating Linux PVH DomU's:
(XEN) AMD-Vi: IO_PAGE_FAULT: domain = 0, device id = 0x2600, fault 
address = 0xfffffffdf8000000, flags = 0x8
As such, I think we're back to zero clues at the moment as to what is 
going on.
Suggestions welcome :)
