Boot freeze screenshot

FreeBSD 11.3 and higher versions deployed as a VM on vmware platform can get
stuck when configured with a single CPU/single core as soon as a cdrom drive is
attached (Tested on ESXi 6.0, ESX 6.5 and on VMWare Workstation 15 Player).

Notice that the VM doesn't crash but just hangs in the booting process as
indicated in the attached screenshot.

This issue was likely introduced by the fix proposed for the following issue
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219857 since previous build
are not affected.

This is not critical as several work around are available: adding a CPU or
detaching the cdrom do the trick, but this might have other unidentified side
effects.
