it was happening to me with an atheros chip and ath5k module. Removing
NetworkManager in favor of WICD solved the issue, so I am pretty sure it
was the trouble maker.
Before the freezes I used to see a lot of rapid disconnect/connect
cycles in the logs.
This first happened on an Ubuntu Intrepid box (wife's box), and the
issue is still there in "Jaunty", so it would be no surprise that it
shows up in Debian too. At the time Ub forums were full of likewise
experiences with various wifi chips, in almost every case shifting to
WICD solved the problem...

Hope it helps,
