You can try this kernel: http://koji.fedoraproject.org/koji/buildinfo?buildID=273960 it contains 2 patches for bug 731365, which help with some instances of rate_control_send_low WARNING, but some others are still unresolved.
Here is another kernel for test. I believe it should fix this bug, please test: http://koji.fedoraproject.org/koji/taskinfo?taskID=3536998 Note you can install it on fedora 16 using either "rpm -ivh --oldpackag" or or "rpm -ivh --force"
