I believe this problem is fixed by 3.6.3-2 kernel: http://koji.fedoraproject.org/koji/buildinfo?buildID=361643 Please test.
I hope this bug is fixed now in 3.6.5, if not please reopen this bug.
Stanislaw -- I'm seeing this on a Samsung Series 9 with F17 with kernelversion 3.6.10-2.fc17.x86_64. I know that isn't _F18_ but I suspect that the bug hasn't been fixed. P.
I'm almost certain this is a duplicate of some other bug here in RH's bugzilla, but I don't know which one ... Emmanuel?
yeah - 863424 seems really the same. BTW - I have a logs (that has been sent to me privately) that show big rate control issues. We keep using high rates even when the link is really bad... This creates a bad backlog in the queues.
