Bug still exists in today's 5.7 kernel, however it took long enough to
trigger that it managed to write some logs:
"BUG: soft lockup - CPU#0 stuck for 22s!" seems to go back to 2013 or
earlier e.g. https://bugzilla.redhat.com/show_bug.cgi?id=1038929
kvm-pit seemed to be eating a lot of cpu, qemu went defunct, macos guest
got a little further into its boot sequence.
Can we upgrade this bug so it gets some visibility, that's two major
kernel versions its not been fixed in now, let alone commented on.
