Bug#633919: /lib/modules/2.6.39-2-amd64/kernel/net/wireless/cfg80211.ko: cfg80211 calling CRDA drops wireless connection, clears ssid




Moreover, running 'iw event -t -f' seems to make the problem worse ...

One more tidbit, I was running 'iw event' (instead of 'iwevent'), and got:

2011-07-14 20:38 [root@******** miforbes]# iw event
wlan0 (phy #0): deauth a0:88:b4:68:59:e4 -> 16:18:0a:30:23:5c reason 4: Disassociated due to inactivity
wlan0 (phy #0): disconnected (local request)
phy #0: regulatory domain change: set to world roaming by the wireless core upon initialization request
regulatory domain change: set to US by a user request

so there is some "inactivity", but I'm browsing the web normally ...
