I note that the H310 in a test R420 that I have does indeed have a JBOD
option.  This presents a disk as /dev/mfisyspdX which is totally
befuddling.

On our stable/9, we get crash and burns with kernel panics and data
corruption, but I haven't pursued it enough to be productive.  I did
bump the machine to head and didn't see any difference.
