In good versions (27e18b8952f8b7a1e26350846f8a0d5a9b33bfb8), calls to
x86_cpu_has_work(), likely due to IRQ 0, returned interchanging true or
false.
In bad versions (92d5f1a4147c3722b5e9a8bcfb7dc261b7a8b855), all calls
returned false.

Title:
BSD bootloader halts with hypervisor.framework
Status in QEMU:
New
Bug description:
Guest: FreeBSD 12.0 Install CD
Host: MacOS 11.14.3 qemu master at 90fb864a7df0a9af677352e94f8225f7b03de922
Command arguments:
qemu-system-x86_64 -m 4000m -cdrom Downloads/FreeBSD-12.0-RELEASE-
amd64-bootonly.iso
When qemu was run with -accel hvf, the bootloader would halt after
showing the menu. The bootloader would not respond to any keyboard
events.
Without acceleration option, the bootloader would count down to zero
and proceed.
