[Bug 1759836] Re: systemd-udevd consumes 100% of CPU

[Bored Individual]

Got the same problem on a Dell E6400 Laptop.

Systemd-udevd climbs to 100% cpu usage in minutes, making it verify
difficult and horrible to install, if one can manage to find the
patience, only to find out that this problem persists after the
installation.

I could install after:

systemctl disable systemd-udevd.service
systemctl disable systemd-udevd-control.socket
systemctl disable systemd-udevd-kernel.socket
systemctl stop systemd-udevd.service
systemctl stop systemd-udevd-control.socket
systemctl stop systemd-udevd-kernel.socket
then kill -9 any systemd-udevd process that remained active

After this the installation went fine and fast.

Disabling bluetooth in the bios did not work for me.
Disabling wireless in the bios works to some extend, systemd-udevd takes around ~50% cpu instead of 100%

Downgrade to 4.13 kernel worked like a charm, no problems after that.

I had some problems switching to the nvidia driver, so i had to stick
with nouveau (which works great)
