Hmmm... I am using the exact same rev, but with two RAID0 stripes.
twe0: 4 ports, Firmware FE6X 1.01.18.001, BIOS BEXX 1.06.00.001
on one machine.

I tried yesterday to stress the machine with 25 simultaneous
bonnie -s 500 &

Although the machine was sluggish, it still worked.  Similarly, make -j12 
buildworld worked. In the past when i saw a similar bug, I could reproduce 
it 100% of the time this way.
