Just got into the very same trouble after enabling Jumbo frames for the adapter (ifconfig eth0 mtu 9000). Seems that the sky2 driver isn't capable of working at high data transmission speeds. Resetting mtu back to normal (1500) fixes the issue here. 100% reproducibility.
My adapter is Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/488153 Title: NETDEV WATCHDOG: eth0 (sky2): transmit queue 0 timed out -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
