[SOLVED] RF Kill-related Service Fails

Hello, fellow Archers.

Not really sure what happened here...  Last night I upgraded a bunch of packages, including systemd, and a couple of weird things happened this morning when I booted up.  First of all, during boot my computer printed messages to the screen about what it was loading, even though I set the "quiet" kernel option.  But it gets curiouser and curiouser (I was so startled I forgot my grammar), as one of the messages told me that it failed to load systemd-rfkill@rfkill0.service.  I looked into it a bit, and it looks like I have three such service (rfkill0, rfkill1, and rfkill2).  I have no idea what this all means.  During the upgrade, I was told that changes were made in the naming scheme of network interfaces, but that I wouldn't be affected.

Here's some info, if it helps:

$ pacman -Q systemd
systemd 210-2
$ pacman -Q netctl
netctl 1.4-2
$ uname -r
3.13.5-1-ARCH

So far, this doesn't seem to have affected my ability to use my computer, but I'd like to know what's going on.

I'm also suffering this "issue". OK, it's not a big deal, but I'm quite curious about it. The interesting part of it is that disabling the offending systemd-rfkill@.service service has absolutely no effect: the service gets itself enabled on boot again without any user intervention.

Re: [SOLVED] RF Kill-related Service Fails

OK, I think I have a solution for this annoyance, at least on my ASUS laptop. The problem seems to be that the asus_nb_wmi fails to be loaded sometimes, so the best is to force it to be loaded straight up from the initramfs.

First, make sure that asus_nb_wmi is loaded into your system:

# modprobe asus_nb_wmi

Check if the Wifi LED gets on. If it did, then all you need to do is to specify the asus_nb_wmi module to be included at the initramfs by including it into the MODULES line at /etc/mkinitcpio.conf:

MODULES="... asus_nb_wmi ..."

Finally, recreate initramfs:

# mkinitcpio -P

Reboot: the systemd warning should be gone now and the Wifi LED light should be working correctly.

Re: [SOLVED] RF Kill-related Service Fails

Fixed the problem, thanks a lot!  I should have mentioned that errors didn't appear if I removed asus_nb_wmi from my /etc/modules.d/.  Of course, that wasn't a viable solution because I like seeing my WiFi LED .  It's so nice to be able to boot without seeing any [FAIL] messages!
