First thanks for your work on this port.

Unluckily after upgrading the bhyve flavor package to the latest version
(202308), the Windows 10 Pro Virtual machines I have running under bhyve
stopped working. They were crashing on boot with error 0xc0000225. I did blame
windows for this, but I was also unable to boot the official windows 10
installation media to try recovery or a new installation.

The installation media was showing a blue screen, 100% vcpu usage for  while
and then crashing.

Googling around there were indications similar behaviour was showing up also on
physical machines with buggy UEFI BIOSes.

At this point I noticed the edk2 port provided UEFI firmware was recently

I have now reverted to the previous version (202202), grabbing the port before
commit 8097dda40a03b8a27a1edf1f31a8af0455a52baf , and the windows VMs are now
working fine again without need of any change.

I think this regression should be investigated, at least. Maybe upstream
already has a fix for this?

If any further information is required please ask.

Thanks in advance!
