Okay, thanks.

Another problem I've noticed (don't want to start a new thread):

Before the latest commit, I've never seen dropouts in the connnection.

But now I've seen for the second time that the connection drops for some 
seconds. ifconfig shows no IP address. At least it recovers, but open 
connections die.

In dmesg I see:

Jun 15 10:34:25 something kernel: iwi0: firmware stuck in state 4, resetting
Jun 15 10:34:25 something kernel: iwi0: link state changed to DOWN
Jun 15 10:34:28 something kernel: iwi0: link state changed to UP

Is this a known issue? Do you need any more info?

Stefan
