systemd-udevs 100% CPU usage

[corsairetc]

Hello I am running Ubuntu 18.04 x64. Everytime I turn on wifi CPU usage is 100% by process:

/lib/systemd/systemd-udevd
If I turn wifi card off system resources is normal. Lan network is not affected this problem only wifi is.
My wifi card model is:

description: Wireless interface

vendor: Intel Corporation
physical id: 1
bus info: pci@0000:0c:00.0
logical name: wlp12s0
version: 00
serial: 00:XXXXXX

resources: irq:26 memory:f69fe000-f69fffff

What could be wrong ?
Thank you for help.

are you using a external mouse?
if so then try disabling the touchpad in settings-> devices-> mouse

just remembered sometimes it's bluetooth, you can try disabling that.

a reboot might be required.

Thank you lot. It was bluetooth I disable the blootooth and now it is ok.

welcome to testing, glad it's okay now. hope the fix by release.

Wasn't fixed by release day, but turning off bluetooth is a viable workaround. Unless you need bluetooth.

thanks, turnoff bluetooth and now it is ok.

Instead of turning off bluetooth, try stopping and starting soon after booting by running the following commands-

sudo systemctl stop systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket

sudo systemctl start systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket

It has worked in my laptop and all the problems are gone.
