no changes in kernel config. I've reviewed pktgen changes and couldn't
find something that would cause the problem. It always only
atomic_inc'ed the ussage cound (and decrements only in error path) which
is perfectly fine.
As for e1000 and or generic TX path changes, I don't have the time to
review them now, sorry :( That's why I posted it to netdev, to let
people who have an idea about the committed changes know that there is
an issue.
Cheers,
Harald
