I've got one of these at home, and it's been giving me grief with
Fedora Core 6 (also tried with the F7 kernel).  My access point is
a FON, which works pretty well with my wife's XP laptop & Belkin
PC-card and my work laptop and Belkin PC card.

However, with my PC, it associates with the access point, signal
strength of about -70dB, and passes traffic fine.  For a few minutes.
Then it simply stops either transmitting or receiving data - I'm
not sure which yet.  athstats and athdebug show that it is still
receiving beacons successfully and iwconfig shows it as associated.
athstats shows about 900-1000 phyerrs per second, which seems a bit
high to me.

To get traffic flowing again, I stop the wpa_supplicant, which 
downs the ath0 interface, bring up the interface again and 
start the wpa_supplicant.

This is with an FC6 2.6.20-ish kernel.  If I use the F7 kernel or
the latest FC6 kernel (2.6.22-something), the machine freezes up
for anywhere between a few seconds and a few minutes every few minutes.
Running "watch -n 1 cat /proc/interrupts" shows a blast of interrupts
from the wifi card at the same time as these freezes.

I'm using the madwifi, madwifi-kmdl and madwifi-hal-kmdl packages from 
atrpms.

One of these days, when I get a chance, I'm going to run wireshark on 
a laptop and see if I can determine if it is frame transmission or
reception that is failing.

Ideas?

Later,
Kenn
