Also, we have repro'd at least one type of watchdog inhouse. One question, is this problem only happening for those running STABLE with the 6.6.6 merged driver? We found the problem does not seem to happen on 7.0. Right now my suspicion is that the FAST irq handling is again causing a problem. I am experimenting with variations to the code today to be sure whats going on, and hopefully fixing it. Cheers, Jack
