I've attached the dmesg dumps from DragonFly and FreeBSD 5.2.1 and 
included the output from "acpidump -t". I've made a little progress.

I've updated to current and rebuild the world and kernel.
A lockup can be prevented by first running "ifconfig wi0 ssid STATION 
mediaopt hostap" and then "ifconfig wi0 inet 192.168.100.1 netmask 
255.255.255.0". This results in livelock errors but doesn't completely 
lock up the machine. Just assigning an IP address still results in a 
complete lockup.

The specification of the PCI riser states that;

"EXT-PCI 1 (lower slot) uses the system resources of the PCI slot on the 
motherboard. EXT-PCI 2 (upper slot) uses Device 19 and INT A, and is 
supported through the latest EPIA BIOS"

Using EXT-PCI 2 is causing all the trouble. I'm going to see if bridging 
has the same effect.

Regards

Gary
