Hard Hang, nothing in logs / no panics

Fri May 11 20:00:26 UTC 2007

Good Day everyone.

I have this one system setup with If_bridge to filter traffic. It does work 
quite good.  I am running FreeBSD 6.2 but as a TINYBSD Image.  The one 
problem I have is I place the machine at the perimeter on our network with 27 
seats.  At that time anywhere between 15min - 24hours the entire system goes 
into a Hard Lock (Physical reboot needed).  The thing is there is no logs or 
kernel panics or anything.  No IRQ Conflicts exists.  

I am looking for any inputs or any ways to go after looking how to even 
diagnosed this.

Here is a copy of my dmesg.
