"hang" means that neither ctrl+alt+esc nor ctrl+alt+del works?

That sounds new...

ACPI_ALL_DRIVERS only enables debugging output from OS implementation
and not in ACPI-CA components, but before using ACPI_ALL_COMPONENTS,
you might want to narrow down the components having problems in the
new ACPI driver (or the screen gets flooded with function traces).

Does any of the following command in the boot loader make the boot
proceed any further?
set debug.acpi.disabled="ec"
set debug.acpi.disabled="cmbat"
set debug.acpi.disabled="acad"

It's a space-delimited list of sub-driver names mentioned in the output
from "man acpi | less +/sub-".

BTW, what was the manufacturer and the model of your mainboard/PC/laptop?
