Well, this kept getting worse and worse. Newer kernels were much "better" 
provoking the HW crashes, but a few days ago I started seeing it even with 
very old kernels, which used to be rock stable.

I first ruled out a firmware update to be the cause.

So I dismanlted the notebook and replaced the wifi chip with another one 
(also driven by iwlwifi), and no failure after 2 days so far.

So it might turn out that this particular one was a red herring. If it 
happens again even with the replaced chip, I'll report back. Sorry for the 
noise.
