Johannes, what should be preventing this from happening?

Comment 7 Johannes Berg 2011-07-13 07:33:54 UTC

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().

opened eclipse

Comment 9 Josh Boyer 2011-09-26 19:29:35 UTC

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?
