Oops... I should have noticed this... Don't ask me how, but when I imported the 2002-09-12 release into my own cvs I somehow managed to update only _some_ of the files in the project. As a result, I ended up with half cvs snapshot and half 2002-09-12 release. Apparently this could do some nasty things with the driver. Funny though that I didn't get any compilation errors/warnings... Anyway, after doing a new import everything works great. Sorry to bother you all with this. (Btw, I hate cvs... ;-)

For interested I have answered Jouni's questions.

Sorry... Wasn't clear about that. I got like a hundred of those messages, and then a reboot without a warning.

Correct. other_ap_policy=2

This is definately related to the ping. The address belongs to the "pinging" client.
