Hi. I'm occasionally seeing the following transmit time-out from a forcedeth
ethernet interface with linux 2.6.30.4. We have a cluster of identical machines
with Supermicro H8DMT motherboards on which there are two such interfaces
integrated, and these errors appear on random machines across the cluster,
about once every two or three weeks per machine.
Following this error, it is impossible to ping in or out, but it is restored
back to life by a simple
ip link set eth0 down
ip link set eth0 up
The eth0 is enslaved to a bridge and has the mtu set at the default 1500. A
second forcedeth nic in the same machine with mtu set at 9000 and not joined to
bridge doesn't seem to suffer from this problem, although it may have much
lower traffic in any case.
