I'm just testing 2.6.36 and getting the same behaviour.
However the wireless seems to connect and be more reliable than 2.6.34 in
spite of the warning.
It would be nice if this could be corrected as it always casts doubt on the
stability of the system when you get unexplained errors and warnings.

Cheers Mike.

Dear Giovanni,
No I haven't been able to find a fix for the warnings.

Another problem I'm having is when an AP is out of range or can not be
connected to I get a message on the console every few seconds:
'cfg80211: Calling CRDA to update world regulatory domain'

This is very annoying as it makes the console unusable. can the information
be made none volatile or suppressed when no connection can be made?

Cheers Mike.
