Curious...if you ping a .local address before the failure, it is
still accessible after other .local addresses become unavailable?
I'm wondering if mdns results might be cached...

The .local address relationship suggests multicast DNS, which suggests
that ath5k might have a problem where it stops receiving multicast
frames.  Does this "ring any bells" for anyone?
