Boot message: Unable to register miscdev on minor = 130

On my new Arch linux installation I was getting a line saying "Unable to register miscdev on minor=130 (err=-16)". In /var/log/errors.log, I was getting the following lines:

Mar 28 19:37:16 localhost kernel: [13926.292770] watchdog: error registering /dev/watchdog (err=-16).
Mar 28 19:37:16 localhost kernel: [13926.292771] mei: unable to register watchdog device.

A comment on Archlinux forum clarified that it was caused because the kernel supports only one watchdog. The solution is two blacklist MEI driver. That can be done using the following line.

echo blacklist mei > /etc/modprobe.d/mei.conf

You read more about IMEI here.
