Victor, your bug is now #677880.

Interesting.

Ok, so either both drivers have a similar bug (or common code they
both call is broken) or there is something in the environment that is
responsible for both sets of symptoms.  Either seems possible.

Now I'm getting lost.  Can you please summarize:

 - what the setup is like --- what are the relevant machines, what
   kind of wireless router, etc

 - what kind of card each machine uses

 - what kernels you have tried on each machine and what happened with
   each

Then for concreteness, let's focus on getting this fixed on a single
machine and card (e.g., the first with the iwlwifi adapter) and go
from there.

Hope that helps,
Jonathan
