Hmmm... well... this is very repeatable.  This controller now has
nothing but the ARRAY of LVD drives using the vendor's cable and
terminator.  I have another LVD cable and terminator (take came with
an HP DAT drive)... I'm going to try them...

Basically, cd'ing to a directory on the raid drive and doing

dump -0af - /usr | team 1m 8 | restore rf -

will cause the problem very repeatably.
