I've seen irregular behavior with sata hot plug recently on oi_151a3

what I've observed so far is that a hot plug and configure into a port that's
initially empty at boot seems to work ok, as does a unconfigure and unplug.

Once you've unplugged once, a second hot plug operation into the same port
appears to succeed, but I/O to that disk hangs; the disk is stable after a reboot.

I haven't had a chance to dig into this further.  My experience was with a
SuperMicro X8SAX motherboard.
