The second one did not trigger (I had actually been using ACPI_VPRINT
for a while to get info like that). I have a dump of my ASL here:
http://home.satanosphere.com/bsd/jeremy.asl.gz. As far as my dmesg goes,
I can get you one where it boots w/ ACPI disabled, but when it hangs, it
hangs before / is mounted at all, so I can't really get it. Should I
boot it again and just type the last lines out?
