I suppose you mean the one with the hot-swappable disks?

Yes; we got similar results until we upgraded the system BIOS and the 
controller firmware (both are available somewhere on hp.com).

We're now having a different problem; once -CURRENT (or 6.2-RC1) is 
installed and running, the disk performance is abysmal. I/O-wise it is 
maxing out around 6MB/sec, which seems far from impressive.

We have tried both with and without RAID configured through the 
controller (i.e., with RAID-1 and with just two seperate disks), and 
results are identical.

There does not seem to be any spurious interrupts, and there is no load 
on the system when doing disk I/O. This is for -CURRENT as of yesterday 
evening (after the latest commits to dev/mpt).
