I didn't try that by now, but I tried current linux git where
a lot of things went into, I am running on top of 7670c7010c.
With that I get:
- two different kernel bugs, the first one actually appearing several
times
- after a short time no package goes out, but the addapter still believes
to be associated.
Here is the dmesg output of the two kernel bugs and the following
hard reset.
BTW, that happened at the *critical* access point at the university.
At home I was before running hte same kernel without problem.
BUt it might be a suspend/resume problem, too, as I suspended the
computer and woke it up here.
