Unplugging the mac mainframe will drain the PCI buss power more so than just a power down and reboot. I've had several times when Kona card etc... would lose audio for FCP. No amount of restarts seem to eliminate the problem but unplugging the mainframe for 10 secs or more would cure the problem. I've also been told to hit the power button on the mainframe with it unplugged to really drain the residual buss power. It's the digital equivalent to "A Swift Kick In The Behavioral Gland!" Perhaps when you unplugged your system this was happening to the Avid SAS interface card. Just guessing here. And as always the Avid Qualified Sacrificial Chicken could help. ;-)
