Yes, It doesn't go beyond that selection most of the time.

That is exactly where I am, at that screen when I make the selection
(any selection) it just pauses for about 30 Secs before the computer
shuts down. Tried all options including 'set hint.acpi.0.disabled="1"'
followed by 'boot' at the loader prompt. Its more or less 1 successful
boot in 7 attempts, totally random, not dependent on w/o ACPI is
picked or not, sometimes it just works with verbose logging or normal

It is definitely something to do with the RESET BIOS timer (If at all
there is anything like that) expiring before FreeBSD kernel can fully
load or something... Thank you HP !
