Subject: Seeing transmit timeouts on 8139cp

  I know that 2.6.27.49 isn't particularly recent, but we have toolchain issues stopping us from jumping to 2.6.33.

That said, if there's a simple fix or two for this, we're happy to backport it, but I wasn't able to track it down.

Does this look familiar to anyone?

Thanks.
