Because the watchdog timeout indicated missing interrupts msk(4) didn't take actual hardware reset. If MSI work without problems it may indicate hardware is in stuck condition under heavy loads. I thought I fixed this kind of issue long ago as increasing FIFO threshold to flush received pause frames seemed to fixed the issue. I'll have to think again. -- Regards, Pyun YongHyeon
