Got a new Dell XPS 401 laptop today and booted amd64 -current bsd.mp
off of a usb stick. It immediately blew up in acpi. bsd.rd did not
blow up.

There seems to be a minor (i.e. non ddb> causing) issue prior to
acpivideo:

acpiec0 at acpi0
acpicpu1 at acpi0: PSS

Disabling acpivideo via ukc makes bsd.mp boot.

tar of acpidump files attached.

Note that the NVidia 425M is only recognized because I added that
to pcidevs.

don't forget to send the amldump

Bad AML. Looks like it is trying to do an AML Load of a memory block, and that
is failing.
Usually that's because the checksum is incorrect.  Look at dsdt.c:aml_load()
and put printf's at both goto fails', to see what is failing.

Not much I can do about it now as I am in Palau. :)

It does seem to be a failing checksum. acpi_maptable() fails in
acpi_load(), in the "Load SSDT from memory" section. A bit of memory
228 bytes long.
