Can you drop into DDB by pressing CTRL+ALT+ESC here?  If so, please
type in `trace' command on the DDB prompt and show me the first several
lines displayed.

As a workaround, you can use `debug.acpi.disabled' knob in the boot loader.
Try ec, cmbat, thermal, sysresource, acad, or any combination of them first
(space-separated).
The list of other possible sub-devices can be obtained by the following
command:
$ man acpi | less +/sub-devices

And please send me the output of the following command:
$ acpidump -dt > foo.asl

Cheers.
