ACPI Panic on Current, AMD64

Hello there,

I've tried to boot 2009-05-20 AMD64 current, but it crashes out. I  
can't produce a full dmesg as  the screen scrolls too quickly for me  
type, and I don't have a serial console. If there's any other way to  
capture the full dmesg, please let me know. This is as much as I can  
see:

System hardware:
CPU: AMD X2 4600
Motherboard: Foxconn C51XEM2AA. Latest BIOS. Uses the Nvidia Nforce  
590 SLI chipset
RAM: 2x1GB 533MHz modules, 1x1GB 800MHz module

The system works under 7.2-Stable, hower the first 4 sata ports don't  
detect hdds (the last two do), but are present in atacontrol. I was  
hoping this was fixed in current, which is why I downloaded the  
snapshot.

Please let me know what other information I can provide.
Kind regards,
Timothy.
