I too had issues with this, but as the OP realized it was a fader calibration command that was executed at the reboot of the ware. I could not find a release note page for this firmware, which I normally look at prior to the flashover. I would have been great to publish this, so we had seen it. PS was however so awesome in helping out with this. People reading this just need to do a fader calibration post install and you are ready to rock.
