ath0: device timeout

[Paul Ripke <stix%stix.id.au@localhost>]

I'm after ideas... I have an otherwise mostly stable netbsd-4 box
with an ath0 card running hostap for my home network. I recently got
a Android G1 phone, and since getting it, my MacBook Pro laptop
(OS X) frequently times out wireless connections (eg. ssh). It might
be 2 minutes, it might be an hour.  Meanwhile, an ssh session from
the G1, attached to the same screen session is fine. If I turn the
wireless off on the G1, the laptop stays connected fine.

Whenever the laptop times out, I get "ath0: device timeout" to syslog,
although connections from the G1 are fine. It's usually a while before
even pings from the laptop come through. I've captured some of the
timeouts with debug enabled on the interface - log is available to
anyone that wants to take a look.

The card is:

I love deadlines. I like the whooshing sound they make as they fly by.
