Debugging 5.2 Beta

[Benjamin Close]

Hi All,
    Just grabbed the 5.2Beta mini iso. Sadly the machine I tried it on 
caused a panic during kernel boot.
A boot -v shows the last lines as (hand transcribed):

PNP0700: ading dma mask 0x4
pnpbios: handle 10 device ID PNP0700 (0007d041)



Fatal trap 9: general protection falut while in kernel mode
cpuid=0; apic id=00
instruction pointer = 0x58:0x1023
stack pointer = 0x10:0xf80
frame pointer = 0x10:0x0
code segment = base 0xc00f0000, limit 0xffff, type 0x1b
    = DPL 0, pres1, def 32 0, gran 0
processor eflags = interrupt enabled, resume, IOPL=0
current process = 0 (swapper)
track number =9
panic: general protection fault
cpuid = 0;
uptime: 1s

Tried turning PNP off/on in the bios, tried toggling hint.acpi.disable 
0/1, not luck.
Quick stats: P4 3G with HTT, 1024MB ram. MPTable: < Springdale-G >, 
pnpbios 15 devices,
FreeBSD 4.9 runs nicely on the box with the attached dmesg.
The box has a Promisc SATA Raid controller (which isn't detected under 
4.9) which I'd really like to get working hence the attempt at 5.2.
Any way to drop to DDB go get better traces? as 
debug.debugger_on_panic=1 & debug.witness_ddb=1 do nothing.

Cheers,
    Benjamin
