It's not that serious... I know that the FEC ethernet driver is
horrendously racy (I have had a patch set for about the last six months
which fixes some of its problems) but as I've had a lot of patches to
deal with, and it's been pushed to the back of the queue...

The races don't lead to data corruption though, merely timeouts and
some lost packets.

Now because things have changed during the last merge window, I've got
an even bigger problem sorting through that patch set and getting it
back into a submittable state.  I've just sent out v2 for it onto the
netdev@...r.kernel.org mailing list.

The initial version (marked RFC) attracted very little interest from
testers, or acks.  I'd very much like to have some testing of it, so
if you want to try it out, I can provide you with a git URL, patches
or a combined patch.
