iwlwifi firmware problem

[Allin Cottrell]

With current systemd and Linux kernel I'm seeing a problem
with loading the iwlwifi firmware at boot time:

[ 14.236171] iwlwifi: Intel(R) Wireless WiFi Link AGN driver
for Linux, in-tree:
[ 14.236174] iwlwifi: Copyright(c) 2003-2012 Intel

'iwlwifi-6000g2a-5.ucode' failed.
[ 14.717117] iwlwifi 0000:03:00.0: no suitable firmware
found!

This is on a ThinkPad T420s. After booting is finished I can
modprobe -r iwlwifi and reload the module, then the firmware
loads OK (version 18.168.6.1, iwlwifi-6000g2a-6.ucode). But it
would nice to have it "just work". Any suggestions? Thanks.
