Subject:  sata_mv hotplug flaky?

Not sure what the latest status of sata_mv hotplug should be, but it 
seems close.  I'm currently running 2.6.24-0.81.rc4.git7.fc9 with a 
MV88SX5081.  Pulled a couple drives and re-added.  One device got 
re-added, but the other did not.  It seems like I got the system to 
probe and re-add the first drive by doing a "mount -a", but haven't been 
able (no idea how) to re-add the second.
