Comment 84 for bug 564376

As it turns out... it's not really gone. It's just that it takes more time for the wireless adapter to lose the connection. And in fact, as it is now NetworkManager doesn't appear to notice that the connection has been lost, but the adapter stops working.

See attachment for the kernel logs... after the last 'On demand firmware reload', the connection would no longer work and the system would need a reboot in order to have it working again.
