New warning on boot time, because of Thinkpad OSD setup?

After recent upgrade I started to get a warning on boot:

$ grep -F nvram /var/log/boot
Fri Nov 25 13:24:05 2011: :: Waiting for UDev uevents to be processed    [BUSY] udevd[241]: kernel-provided name 'nvram' and NAME= 'misc/nvram' disagree, please use SYMLI

Seems that it's caused by /etc/udev/rules.d/tpb.rules, which I created (long time ago, when I installed Arch) according to https://wiki.archlinux.org/index.php/ThinkPad_OSD

$ cat /etc/udev/rules.d/tpb.rules
KERNEL=="nvram", NAME="misc/%k", SYMLINK+="%k", MODE="0660", GROUP="users"

Can someone suggest what I should do to eliminate the warning? I don't understand what the warning message tries to tell me on boot time.

Feel free to tell me if I should choose other forum for this topic.

The NAME="misc/%k" rule should be removed.

Re: New warning on boot time, because of Thinkpad OSD setup?

I do not get the error and here is what I have in /etc/udev/rules.d/51-arch.rules

KERNEL=="nvram",   NAME="misc/%k", SYMLINK+="%k", GROUP="kmem", MODE="0666"

I have nvram in the DAEMONS line of /etc/rc.conf

It's all irrelevant to me though because tbp refuses to work.  I got xosd to work by installing xosd-2.2.14 from source, but I can't get tpb to work.

nvram is a module, not a daemon. I can only assume you're not actually paying attention to your logs or bootup messages, because NAME= rules are forbidden by the kernel and rc.multi will throw an error about your bogus daemon name.

Re: New warning on boot time, because of Thinkpad OSD setup?

nvram is a module, not a daemon. I can only assume you're not actually paying attention to your logs or bootup messages, because NAME= rules are forbidden by the kernel and rc.multi will throw an error about your bogus daemon name.

I am not seeing any error messages related to NAME= or nvram.

Right file, wrong place: you are correct about nvram being a module - I misread the wiki page.

Regarding NAME= rules being forbidden, I didn't know that.  The Wiki page for Arch ThinkPad OSD says to put it in there.

At any rate, the tpb OSD still doesn't work for me.

Re: New warning on boot time, because of Thinkpad OSD setup?

It's me again. I removed NAME="misc/%k" and on the next boot got a different warning:

Sun Nov 27 13:40:58 2011: :: Waiting for UDev uevents to be processed    [BUSY] udevd[246]: device node '/dev/nvram' already exists, link to '/dev/nvram' will not overwri

If I remove tpb.rules completely, after reboot tpb stops working, maybe because of different access rights:

$ ls -l /dev/nvram
crw-r----- 1 root kmem 10, 144 2011-11-27 13:42:58 /dev/nvram

So, the problem is not solved.

David Batson: tpb is working for me (with tpb.rules given above and "nvram" in MODULES). It even works despite of the warning about nvram during boot.

Re: New warning on boot time, because of Thinkpad OSD setup?

I also removed the SYMLINK= part, and the warning disappeared, and OSD works. Thanks for your help!

For reference, my /etc/udev/rules.d/tpb.rules now contains

KERNEL=="nvram", MODE="0660", GROUP="users"

Re: New warning on boot time, because of Thinkpad OSD setup?

Maybe tpb OSD just doesn't work with the Lenovo X220 ThinkPad or with XFCE.  I had it working in the past with my T42 ThinkPad in Fedora 14 Gnome (2) and Mandriva 2010.2 KDE.  When I get a chance in some weeks from now, maybe I'll install Arch XFCE on there and see if tpb OSD works.
