Following a suggestion, I carried over a few tests with DEBUG and
LOCKDEBUG enabled. This did not make any difference; starting a 64-bit
Linux guest still hard-locks the machine; starting a 32-bit Windows 10
guest keeps it sort-of alive, responding to pings and able to switch
between tmux windows, but no further i/o is possible; in this case one
is able to go into the debugger and initiate a dump, which then failed
for me after the first output line.
