It's basically reporting random garbage for the identification data for the port multiplier. I don't know what went on there but probably the controller needed a strong kick in the butt to come back into sane state. Anyways, there isn't much the port multiplier layer can do if the controller is reporting garbage for data read from PMP. Mark, have you seen anything like this? Could it be that the controller goes out of proper configuration after certain condition and needs to be reset/reconfigured?
