Hi
I've now tested with the mainline kernel and the problem persists
exactly as described before.
Regards

** Description changed:
network-manager seems to be disconnecting my wifi link very often,
(every 2 minutes or so). When looking at "iwevent" output this seems to
be each time nm does a scan. This is the iwevent output starting from
wifi disabled in nm and then enabling it, stopping after the first re-
connect:
