I've been using AMD CPU's pretty extensively since the early 90's - back
then I was running NeXTStep and out of the three Intel alternatives it
was the only one which ran properly. Never seen anything like this
before now though. In particular this Ryzen replaces the CPU on an old
Phenom II - i.e. its the same disc and hence the same OS and VirtualBox
config - and that ran fine.
So theres something odd about the Ryzen here.
Am also not sure its to do with the virtualisation - I got my first
lockup with no virtualisation going on at all. Disablign SMT and the
system hasnt locked, despite heavy virtualbox use.
