I had explicitly turned it off, but when the NIC was in its bad state em1: flags=8843 metric 0 mtu 1500 options=2198 ... its back on along with TSO? Not sure if its coincidence or a side effect or what. For now, I have had to re-purpose this nic to something else. debug info shows Jan 28 00:25:10 backup3 kernel: Interface is RUNNING and INACTIVE Jan 28 00:25:10 backup3 kernel: em1: hw tdh = 625, hw tdt = 625 Jan 28 00:25:10 backup3 kernel: em1: hw rdh = 903, hw rdt = 903 Jan 28 00:25:10 backup3 kernel: em1: Tx Queue Status = 0 Jan 28 00:25:10 backup3 kernel: em1: TX descriptors avail = 1024 Jan 28 00:25:10 backup3 kernel: em1: Tx Descriptors avail failure = 0 Jan 28 00:25:10 backup3 kernel: em1: RX discarded packets = 0 Jan 28 00:25:10 backup3 kernel: em1: RX Next to Check = 903 Jan 28 00:25:10 backup3 kernel: em1: RX Next to Refresh = 904 Jan 28 00:25:27 backup3 kernel: em1: link state changed to DOWN Jan 28 00:25:30 backup3 kernel: em1: link state changed to UP ---Mike
