A way to reproduce (without NM):

* Start scanning in a loop
while true ; do sudo iwlist scan ; done

* press rfkill - scan hangs forever.
* press rfkill again - doesn't help

I have acer 5720G with hardware rfkill.


The problem seems to be that if user presses rfkill during scan, it
hangs.


How about rate control issues I still see, do you know why upload is
slower that download?
