Please swap the third and fourth drive and see whether the problem moves
with the drive or stays with the port.  Also, please verify regular
powered on detection (array up and running before detection begins)
always works.  4726 is very quirky (it ate up a LOT of development /
testing time) and I guess we'll have to accept some brokenness.

Thanks.
