I've recently rebuilt to r336294 which still exhibited the problem, with periodic logs such as these: Jul 26 04:09:53 strawberry kernel: em1: Watchdog timeout Queue[0]-- resetting Jul 26 04:09:53 strawberry kernel: Interface is RUNNING and ACTIVE Jul 26 04:09:53 strawberry kernel: em1: TX Queue 0 ------ Jul 26 04:09:53 strawberry kernel: em1: hw tdh = 524, hw tdt = 544 Jul 26 04:09:53 strawberry kernel: em1: Tx Queue Status = -2147483648 Jul 26 04:09:53 strawberry kernel: em1: TX descriptors avail = 1004 Jul 26 04:09:53 strawberry kernel: em1: Tx Descriptors avail failure = 0 Jul 26 04:09:53 strawberry kernel: em1: RX Queue 0 ------ Jul 26 04:09:53 strawberry kernel: em1: hw rdh = 172, hw rdt = 170 Jul 26 04:09:53 strawberry kernel: em1: RX discarded packets = 0 Jul 26 04:09:53 strawberry kernel: em1: RX Next to Check = 171 Jul 26 04:09:53 strawberry kernel: em1: RX Next to Refresh = 170 Jul 26 04:09:53 strawberry kernel: em1: link state changed to DOWN Jul 26 04:09:54 strawberry kernel: em1: link state changed to UP Jul 26 04:10:20 strawberry kernel: em1: Watchdog timeout Queue[0]-- resetting Jul 26 04:10:20 strawberry kernel: Interface is RUNNING and ACTIVE Jul 26 04:10:20 strawberry kernel: em1: TX Queue 0 ------ Jul 26 04:10:20 strawberry kernel: em1: hw tdh = 0, hw tdt = 358 Jul 26 04:10:20 strawberry kernel: em1: Tx Queue Status = -2147483648 Jul 26 04:10:20 strawberry kernel: em1: TX descriptors avail = 666 Jul 26 04:10:20 strawberry kernel: em1: Tx Descriptors avail failure = 0 Jul 26 04:10:20 strawberry kernel: em1: RX Queue 0 ------ Jul 26 04:10:20 strawberry kernel: em1: hw rdh = 0, hw rdt = 1023 Jul 26 04:10:20 strawberry kernel: em1: RX discarded packets = 0 Jul 26 04:10:20 strawberry kernel: em1: RX Next to Check = 0 Jul 26 04:10:20 strawberry kernel: em1: RX Next to Refresh = 1023 Jul 26 04:10:20 strawberry kernel: em1: link state changed to DOWN I'll give r336313 a try as soon as possible and corroborate the fixes!
