What does this mean: Error calling EVIOCSKEYCODE: Invalid argument ??

Asked by Michael Heuberger

When running `dmesg` I often see lines like these:

[ 11.232584] systemd-udevd[490]: Error calling EVIOCSKEYCODE: Invalid argument
[ 11.232646] systemd-udevd[490]: Error calling EVIOCSKEYCODE: Invalid argument

What do they mean and how can we fix this?

Yes and sorry, your search term isn't correct. Should be:
https://duckduckgo.com/?q=%22Error+calling+EVIOCSKEYCODE%3A+Invalid+argument%22

And you'll see only 5 results and none helped ...

I see this when I boot 14.04 :
systemd-udevd[355]: Error calling EVIOCSKEYCODE: Invalid argument
It probably slows booting a bit but if it has other consequences they aren't obvious to me. I have no idea what it means.

I found some information in other web, it seems to be related to a macro for key codes in udev source code, but I am not familair with this. For more information, https://<email address hidden>/msg19342.html . I hope it helps and this is not noise.

Why have you put systemd on the PC anyway?
