Comment 56 for bug 941695

I should have added that I can also confirm that the issue is more prevalent when there is a weak wifi signal. The easiest way to reproduce seems to be to connect to the wifi network and then walk with the laptop away from the AP towards the edge of the wifi range. When the network is hung the load on the machine will go into the 14+ range. Unloading the module with modprobe -r takes a long time, but will eventually unload the module and return the machine to normal where the module can be reloaded.
