This may be totally unrelated; but I was having issues with my port replicator case that sound like this. If I had an HFS volume + ZFS volumes on the same port replicator and hot swapped any combo of them in or out, there were situations that would cause a KP. Removing/Inserting a drive caused the whole port replicator board to do some sort of scan of the drives, halting all IO or unmounting the device or driver or whatnot, that was my guess given the behavior of the activity lights on the board and the logs from the sata card driver before the KP.
