Kernel panic in FreeBSD 6.0 with Samsung SP2504C SATA harddrive

Hello everyone!

The other day I installed FreeBSD 6.0 on my AMD64 3200+ computer with an Asus 
A8N-E motherboard. The system has 1 IDE drive and 2 SATA drives. Installation 
went normally and everything looked fine, but at boot I got a kernel panic:

----------------------------------------------------------------
ad10: 238475MB <SAMSUNG SP2504C VT100-33> at ata5-master SATA150


Fatal trap 18: integer divide fault while in kernel mode
instruction pointer     = 0x20:0xc08100c3
stack pointer           = 0x28:0xc0c20b60
frame pointer           = 0x28:0xc0c20be8
code segment            = base 0x0, limit 0xffff, type 0x1b
                         = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 0 (swapper)
trap number             = 18
panic: integer device fault
----------------------------------------------------------------

After some testing I found that the problem was related specifically to that 
hard drive, I swapped controllers etc, but no change. If I removed that drive, 
FreeBSD would boot normally. I first tried on the AMD64 release, and after that 
I installed the i386 release, but there was no difference. (The included kernel 
panic message is from the i386 release).

But fear not, I found a workaround! Turns out that if I change access mode on 
the hard drive in my bios from "Auto" to "Large", it boots fine. But just 
thought you should know about the issue :)

I'll also include a dmesg of a normal boot of the system with the hard drive 
disconnected, I didnt discover the workaround until more recently:
