A bus trace shows that while executing e1000e_down, TCTL is cleared except for the PSP bit. This occurs while in the middle of fetching a TSO packet since the Tx packet buffer is full at that point. Before the device is reset, the e1000_watchdog_task starts to run from the middle (it was apparently pre-empted earlier, although that is not in the trace) and sets TCTL.EN. At that point, 82571 transmits the corrupted packet, apparently because TCTL.MULR was cleared in the middle of fetching a packet, which is forbidden. Driver should just clear TCTL.EN in e1000_reset_hw_82571 instead of clearing the entire register, so as not to change any settings in the middle of fetching a packet.
