As expected, AMD fixed the problem with VME that affected Ryzen processors. The fix is shipped in the form of a microcode patch as part of AGESA 220.127.116.11, currently being rolled out by OEMs as part of a BIOS update. Which means that depending on the OEM and board, a fix may or may not be available for a given system today.
The patch level for the fixed microcode is 8001126 or higher. The older microcode revision 800111C (part of AGESA 18.104.22.168a) is known to have trouble with VME.
