Well, since I'm testing this laptop for any corner cases, the non-working 
case had actually been tested with things like multiple suspend-to-ram 
cycles (while doing accelerated 3D and sound at the same time), along with 
testing anything else I could think of. And everything worked, but 
wireless wouldn't associate.

Reverting and rebooting, and it worked. But then when I wanted to 
double-check (sadly _after_ having already sent out the complaint), I 
now cannot get it to not work even without the revert.

And I've re-done all the STR testing, and that isn't the cause of it.

Oh well.

I don't actually tend to _use_ that laptop, it gets dug out for release 
and distro testing and for some very occasional travel.  I've not had 
issues with wireless on that thing before (apart from any normal iwl 
issues), but maybe it just happened to take a really really long time to 
associate that one time.
