RTL-8139/8139C/8139C+ (rev 10 As soon as I get both ethernet cards up and running and put any reasonable load (using the system as a packet-forwarding firewall), one or both of them fail for a number of minutes. Eventually, they usually come back up on their own, at which time the following message appears in the syslog: kernel: [ 2242.871816] NETDEV WATCHDOG: eth0: transmit timed out kernel: [ 2245.885704] eth0: Transmit timeout, status 0d 0000 c07f media 10. kernel: [ 2245.885704] eth0: Tx queue start entry 7227 dirty entry 7223. kernel: [ 2245.885704] eth0: Tx descriptor 0 is 0008003c. kernel: [ 2245.885704] eth0: Tx descriptor 1 is 0008003c. kernel: [ 2245.885704] eth0: Tx descriptor 2 is 0008003c. kernel: [ 2245.885704] eth0: Tx descriptor 3 is 00080042.

I read online that sometimes WATCHDOG TIMEOUT means that there is bad network infrastructure of some sort. I have tried many different network topologies, hubs, and cables and it always produces the same error. I have also tried all different possible BIOS settings related to IRQs. Based on advice from online forums and the like, I have also tried the following kernel command line settings, in sequence and together in various ways, and the behavior is still the same: nosmp
