The netdev watchdog notices after a while and is able to reactivate the interface: Mar 15 13:28:12 btd kernel: NETDEV WATCHDOG: eth0: transmit timed out Mar 15 13:28:12 btd kernel: sky2 eth0: tx timeout Mar 15 13:28:12 btd kernel: sky2 eth0: transmit ring 458 .. 435 report=3D45= 8 done=3D458 Mar 15 13:28:12 btd kernel: sky2 eth0: disabling interface Mar 15 13:28:12 btd kernel: sky2 eth0: enabling interface Mar 15 13:28:12 btd kernel: sky2 eth0: ram buffer 48K Mar 15 13:28:15 btd kernel: sky2 eth0: Link is up at 1000 Mbps, full duplex= , flow control both This machine is a Core2 Duo e6700, and the interface is: 03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gi= gabit Ethernet Controller (rev 20) to 1 Gb hub.
