Panic on FreeBSD 6.0BETA1

   Hi all,
I decided to try and help with testing 6-BETA1, after updating sources and
recompiling i get the following during boot up. I am tried booting without
hyperthreading enabled in the bios and I still get the same panic.

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id =00
fault virtual address = 0x480008
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc06923cc
stack pointer = 0x28:0xc10208ec

Code segment = base 0x0, limit 0xfffff, type 0x1b
             = DPL 0, pres 1, def32 1, gran 1

processor eflags = interrupt enabled, resyne, IOPL = 0
current process = 0 (swapper)
[thread pid 0tid0]
Stopped at strlen+0x8: cmpb $0,0(%edx)

I left all the debugging features in the current however, I am not sure
exactly how to trace this problem. If someone could point me to any doc that
would allow to provide more information that would  be great. I updated my
pen 400MHZ using the same procedures and all went well. Please help
