ehci-sched already knows if slots got missed. It is a simple if !(a < b < c) that's checked upon every submit. This check also catches the buffer underrun case in the code as it stands now; missed slots and URBs starving are not treated as different cases in the code, which is part of the source of the original conflation of the two cases. In both cases, a slot should have been filled and wasn't. Monty ------------------------------------------------------------------------- Take Surveys. Earn Cash.
