This is Luis's code, I think it should be prevented by stopping queues in scan but I believe that is racy there due to lack of flushing in-flight packets with synchronize_net().
Package: kernel Architecture: x86_64 OS Release: Fedora release 15 (Lovelock) Comment ----- opened eclipse
I don't see anything that would immediately lead me to believe this is fixed upstream, but it's worth testing the latest F15 2.6.40.x kernel update. Can you recreate with that?
