Can you please do

  udevadm info --export-db > /tmp/udev.txt

and attach /tmp/udev.txt here? That should give me a first clue what system you have and which keymap it is trying to set in the kernel.

I've completely emptied /lib/udev/hwdb.d/60-keyboard.hwdb and still get boot errors of the sort:

systemd-udevd[285]: Error calling EVIOCSKEYCODE: Invalid argument

Each time I edited 60-keyboard.hwdb the error would go away next boot and some number of successive boots but would return with a different line number until the line numbers cited didn't even exist, all the way to an empty file.

It seems merely touching 60-keyboard.hwdb fixes the error for a bit, though I'll have to wait for the next error to confirm that.

[mark wade (markwade)]

I neglected to say I've restored the original /lib/udev/hwdb.d/60-keyboard.hwdb with all its entries intact and have rebooted a few times with no errors. Next error I'll touch the file and reboot and see.

[G.Araucaria (crazy-czap)]

problem apparently gone: i will close this issue

[G.Araucaria (crazy-czap)]

i mean i would like to close it, but i can't :(

Maybe I'm not supposed to post here? But since I did I'll finish up.

It seems to come and go on it's own now requiring no action from me, mostly it's gone. The last was January 12 with:

systemd-udevd[287]: Error calling EVIOCSKEYCODE: Invalid argument

but successive boots yield no further errors of this type or entries in dmesg

<shrug>

[mark wade (markwade)]

Last three boots yielded:

1st boot: systemd-udevd[283]: Error calling EVIOCSKEYCODE: Invalid argument
2nd boot: systemd-udevd[295]: Error calling EVIOCSKEYCODE: Invalid argument
3rd boot: systemd-udevd[287]: Error calling EVIOCSKEYCODE: Invalid argument

touching the file did not prevent a consequent error.

annoying and lengthens boot time.

This bug still affects me on 14.04.2, using Kernel 3.16.0-31-generic using the original /lib/udev/hwdb.d/60-keyboard.hwdb provided by ubuntu and ubuntu updates

This bug still affects me on 14.04.2, using Kernel 3.16.0-37-generic.

I have not manually modified /lib/udev/hwdb.d/60-keyboard.hwdb, but I am not sure it is the original.
