I had trouble on a dual Xeon with a 8506 controller a while back; when 
running find, or unpacking the ports tree, the machine would lock up. 
We did suspect flakey hardware, but it appears to be working reliably 
now. Not sure which of the many things we tried did it.

It's currently running -current from end of May; I will upgrade it to 
RELENG_5 when I find the time, hopefully the next couple of days.
