Hi,

I've been getting these NETDEV WATCHDOG errors at infrequent
intervals (typically every few weeks; sometimes far more often, as has
happened this week), but usually at inconvenient times -- making a TV
recording over NFS, for example. It's usually at some point when the
network and disk subsystem are stressed together.

The network doesn't come back, even if I remove and reinsert the
network card driver. I even bought a new network card with a different
chip, and saw a precisely similar problem from that (I've included
that trace below, too).

These have happened on a range of kernels since at least 2.6.31. I
include a selection of kernel logs, including one from the other
network card. I've seen it on distribution kernels (Debian),
kernel.org kernels, and the btrfs dev kernel (that's the
2.6.34-81023-g2ebc346 version).

Can anyone help me diagnose and fix the problem?

Hugo.
