asus a7m-266d freezes after put under load (SMP KERNEL)

[Ray Hicks]

I am running FreeBSD 5.1-RELEASE P#7 with and SMP kernel and the box seems to 
hang as soon as it is under load for about 2 minutes.   I dont get any log or 
panic signal and the debug.log is empty as well.  I cvsup my sources but I 
cannot build as the machine will halt about 2 minutes into compile.  

Can anyone offer any suggestions?   

asus a7m-266D
dual athalon MP1800+
1 Gig DDR 2100 RAM
Dual WD 120G IDE drives. 

any help appreciated. 

thanks
