This failure is bizarre. The XSA-204 PoC does an emulated syscall
instruction, but the crash here is when executing sysretq to exit from
the syscall handler.
From the Xen boot log, this is a Penryn system. It is 64bit so should
have no problems with syscall/sysret. I see that the ucode is from 2010
so getting on for 8 years out of date
OTOH, I see from the serial log

Which is surely causing all HVM guests to fail, but doesn't appear so
from the other results.
