Not sure exactly where this goes...
                        so, i'm sending it to everyone :P

I've heard tell that there are problems with the VIA chipset and UDMA on 
FreeBSD. Is this true, and if so, what is the problem with?

In my system is:

FreeBSD 4.2-STABLE #0: Fri Dec  8 01:52:44 EST 2000 
CPU: Pentium III/Pentium III Xeon/Celeron (601.37-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0x683  Stepping = 3
atapci0: <VIA 82C686 ATA66 controller> port 0xe000-0xe00f at device 7.1 on 
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0                    
ad0: 19546MB <FUJITSU MPF3204AT> [39714/16/63] at ata0-master UDMA66     

The drive has enough space and I have 512MB RAM. If I hit the system hard, 
lets say, rm -rf /usr/ports, the system locks up. It doesn't just stop 
responding for a little bit. It locks up tight. It kills all network 
connections, doesn't respond to the console and doesn't respond to any 
network activity. A hard reboot is the only thing that can bring it back to 

One time, someone was able to see the console when this happened, and they 
said something about a page fault. Trying to solve this, we ordered two brand 
new 256MB modules and installed them. It is still happening.

This is a production environment type of server. I've had no other problems 
with FreeBSD 4.2-S, and i'm hoping maybe this is something that has been
