These boxes are running -current (from a couple of weeks ago).  I 
haven't tried running it on 5.2.1 yet.  We haven't run this
particular application on anything but -current because there is
not enough driver & disk support on RELENG_4.
I am now running the test with hlt disabled, and will let you know
if it locks up again.
