DFI Lanparty NF4 Ultra-D AMD64

[Christopher Thomas]

Hello,

first time poster, long time user.

System:
DFI Lanparty NF4 ultra-D
AMD64 3500+
1GB GeIL DDR400 Dual Channel
Maxtor 12GB 5400RM
Lite-ON CDRW

Problem:
Can install FBSD 6.0-Release/amd64 and i386 just fine, but upon first 
reboot I get.

Fatal Trap 18: integer divide fault while in kernel mode
instruction pointer  = 0x8:0xffffffff8022b99a
stack pointer         = 0x10:0xfffffff809769f0
frame pointer         = 0x10:0xfffff003b8af800
code segment        = base 0x0, limit 0xfffff, type 0x1b
                             = DBL 0, pres 1, long 1, def32 0, gran 1
processor flags      = interrupt enabled, resume, IOPL = 0
current process     = 0 (swapper)
trap number          = 18
panic: integer divide fault
Uptime: 1s
Cannot dump. No dump device defined.
(hand typed on my WinXP box (same mobo))

My plea:
I have been using FBSD for about 5 years, but I've never had a panic, 
never had a problem installing, so I've had limited experience and need 
to troubleshoot a system. Luckily, I found a problem, and I want to 
learn from it. But still fix my problem. So, if possible, can some one 
help me?

I've disabled what I could, removed everyting but HDD, tried every boot 
option in the boot menu. I have a suspicion that the problem might lay 
in the nf4/nvidia chipset? Maybe the ataraid? But thats just based off 
of the current nf4 problems I've seen. Doing a search for trap 18 only 
brings up trap 12, (with two instances of trap 18 that have no solutions.)

Thank you very much, it is communitis, and lists like this that make my 
mind up about FreeBSD and lets me know why I chose such a wonderful OS.
