kernel trap 12 with interrupts disabled on a fresh SMP -CURRENT

After getting home from a vacation I upgraded my -CURRENT computer
from a Nov 20th kernel to todays kernel. After the new interrupt code
was commited I had to turn off ACPI support because of some vital
pieces are missing in the ACPI implementation in my BIOS (if I
recall correctly it was missing MADT table).
The attached crash is when I boot the kernel WITHOUT ACPI. This was
captured with the serial debugger which generated a series of panics
(I aborted the output after a few of them since they were all exactly
like).
If I boot it with ACPI I get a interrupt storm to irq20 (which
coincidently is ACPI):
[slurp/100] ~> uptime && vmstat -i
9:13pm up 17 mins, 2 users, load averages: 0,61 0,61 0,48
interrupt total rate
irq1: atkbd0 2608 2
irq8: rtc 133761 127
irq14: ata0 881 0
irq15: ata1 30 0
irq17: xl1 8148 7
irq19: uhci0 ahc0 3421 3
irq20: acpi0 41951867 40106
irq0: clk 104528 99
Total 42205244 40349
I have attached mptable and acpidump output too. Any clues?
