Subject: Re: [2.6.26-rc5] iwlwifi 4965 not working - last on 2.6.23

Hi,

After

laptok ~ # echo 0 > /sys/bus/pci/drivers/iwl4965/0000\:04\:00.0/rf_kill
laptok ~ # iwconfig wlan0 txpower on
laptok ~ # /etc/init.d/net.wlan0 restart
 * Service net.wlan0 starting
 * Service net.wlan0 started
laptok ~ # dmesg >dmesg-`uname -r`_`date +%F`.txt


I get in dmesg

...
