** Description changed: Binary package hint: linux-image-2.6.24-16-server I'm running Ubuntu Server on a machine with two network cards acting as a file server and gateway; eth0 is the external (Internet-facing) interface. The system has been running fine for almost a year. Last night, the external interface stopped passing traffic. A "ifdown eth0; ifup eth0" was enough to bring it back to life. This morning, the same thing happened, and it happened again this evening. Since it doesn't appear to be my ISP's problem, I looked at syslog and found the following: Oct 28 01:30:44 marajade kernel: [4799484.682357] NETDEV WATCHDOG: eth0: transmit timed out Oct 28 01:30:44 marajade kernel: [4799484.682362] eth0: Got tx_timeout. irq: 00000000 Oct 28 01:30:44 marajade kernel: [4799484.682363] eth0: Ring at 37578000 Oct 28 01:30:44 marajade kernel: [4799484.682364] eth0: Dumping tx registers Oct 28 01:30:44 marajade kernel: [4799484.682367] 0: 00002000 000000ff 00000003 03aa03ca 00000000 00000000 00000000 00000000 Oct 28 01:30:44 marajade kernel: [4799484.682370] 20: 00000000 00000000 00000000 00000000 00000001 00000000 00000000 00000000 Oct 28 01:30:44 marajade kernel: [4799484.682373] 40: 0420e20e 0000a855 00002e20 00000000 00000000 00000000 00000000 00000000 ... many more lines ...
