Intel 3945 won't work after update.

After updating a Thinkpad T60 with the Intel 3945 wireless card I am unable to connect to wireless. Wicd's GTK front end even fails to start, but the problem is not with Wicd. Anything attempting to access the card will hang, even 'ifconfig wlan0 up' hangs and I have to kill it.

Here is 'lsmod|grep iwl':

iwl3945                63543  0 
iwl_legacy             45018  1 iwl3945
mac80211              203227  2 iwl_legacy,iwl3945
cfg80211              147716  3 mac80211,iwl_legacy,iwl3945

Here is the relevant information from everything.log:

Here is 'ls /lib/firmware/|grep 3945':

iwlwifi-3945-2.ucode

Here is 'rfkill list':

	Hard blocked: no
1: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
2: tpacpi_bluetooth_sw: Bluetooth
	Soft blocked: no
	Hard blocked: no

Obviously it is a firmware issue, even though linux-firmware is properly installed and has been reinstalled from other sources in an attempt to get it working.

Re: Intel 3945 won't work after update.

Do you have a wireless kill switch on your laptop? Does the rfkill status change if you toggle it?

Re: Intel 3945 won't work after update.

Just updated and rebooted, but wireless still seems to be working for me (also have a T60 using iwl3945. Same modules loaded that gozes listed. Here's iwl3945 containing lines in my everything.log since the reboot

I'm running the stock Arch kernel from the core repo right now and linux firmware package is 20120227-1. Let me know if there's other info I can give to try and help track down the difference.
