There is another failure mode.

I think rmmod/modprobe says all:

When I had the card just stop working without crashing my notebook (3.0, 3.1)
I got the same when trying to reload the driver.

I have built and loaded the kernel with this patch. I even have netconsole
apparently working. But ten hours have not elapsed yet. So far so good.

If it works till the 10th, I will test it with roaming, too.
