July 26, 20242 yr Lately I've been testing Windows Vita on AMD Ryzen mobile platform. https://msfn.org/board/topic/186330-windows-vista-on-amd-ryzen-mobile-raven-ridge-vega-graphics-testing/#comment-1269685 The OS is stable once it has booted so it's mostly usable, but this cannot be said about virtual machines running on this hardware. The stability is WAY worse there. It seems that Ryzen issues affect virtual machines running using AMD's virtualization technology way more that the host. Guest machines (Windows 11 and Linux) would randomly hang, endlessly display what was on the screen just before the crash and cause 100% CPU usage on cores that were assigned to the virtual machine. It doesn't harm the host OS, you can just run taskmgr.exe and close the affected virtual machine This makes me think Ryzen issues lie deeper than in the USB controller, CD ROM drivers and the likes. It may be related to no drift correction as on Haswell, I guess Windows build 6519 would have to be tested to know for sure. So far ppl have reported different builds to be the ones that fix the Ryzen BSODs https://board.eclipse.cx/viewtopic.php?p=2910#p2910
