This is likely not an ACPI issue. Are you running with "options INVARIANTS"? My laptop panics on boot without atapicam but with "options INVARIANTS" due to a use-after-free bug in ata. I'll try to track it down when I have time but I don't know the ata code really well. More of the backtrace would be helpful also. -Nate
