Are you talking about this one:
http://marc.info/?l=linux-netdev&m=119482084511178 ?
I attached a forward port to current git.

I am using this patch, and caught this maybe related error while Bittorrenting:

I attached the full dmesg, but I don't think there is any output
caused by the TCP_DEBUG patch.


Cheers.
