@EddieA:
With option 2, Disable acpi, I get EXACTLY the same results as trying to boot pfSense.
So, booting with acpi disabled, it looks like even a "vanilla" FreeBSD can't cope.
Agreed, that one should be pursued with FreeBSD.
@EddieA:
But, with the Default, option 1, it boots into the OS cleanly.
But, for a normal boot, it looks like something in the tailoring, for pfSense, is the issue.
I think this one belongs to pfSense.
Cheers.
