Please don't top post.  You don't have to add things to the loader.conf
file, you can manually do them at boot time with the "set" command at the
loader prompt.

My laptop used to boot fine without ACPI and now no longer boots without
it.  It hangs halfway through the boot sequence.  I haven't had time to
track it down.  Some laptops cannot boot at all without ACPI.  In the
future, PC vendors will not make ACPI optional.

I want the acpidump to look into the ATA irq routing warnings, not sure
about the GPF you mentioned.  Hopefully someone else can look at this.
