Hi,

I have built today a linux-next (next-20101201) kernel which includes
wireless-next-2.6 up to master-2010-11-30.

>From tig utility:
2010-11-30 15:33 Stanislaw Gruszka  [wireless-next-2.6] iwlagn: fix
microcode error on 4965
[main] 61790c5f3c5f158821821a00797d94504531839f - commit 1929 of 226338 (0%)

Unfortunately, my wlan network connection is totally unstable.

$ dmesg | grep "RX AssocResp" | wc -l
216

The block looks like this:
[ 4436.504059] ieee80211 phy0: wlan0: No probe response from AP
00:04:0e:e4:00:3d after 500ms, disconnecting.

[ 4440.684667] wlan0: RX AssocResp from 00:04:0e:e4:00:3d (capab=0x411
status=0 aid=1)
[ 4440.684673] wlan0: associated

My wlan device is an ath5k:

$ lspci -nnvv | grep "Ethernet controller" | grep -i ath
02:02.0 Ethernet controller [0200]: Atheros Communications Inc. AR5212
802.11abg NIC [168c:1014] (rev 01)

Any idea what's wrong? (Just speculating on the last patch-set from Nick...)
How can I help to dig into this problem?
Debug-session with wpasupplicant? Which kernel-parameters (debug) to
be considered/set?

Kind Regards,
