[Bug 1759836] Re: systemd-udevd consumes 100% of CPU
I too can confirm that the solution Florian posted (modifying /lib/udev/rules.d/97-hid2hci.rules) works.

Forgot the quotes around 'EOF', tested and it works for me.

Is this launchpad thing even working, how long does it take to fix a bug around here ? This is untested but should work, let me know. Execute the following commands, it will create a file called bugfix-1759836.service. Copies it to /etc/systemd/system and enables it. --- cat

Still present in 4.19rc6, lets hope it gets fixed before 5.0. If you guys want me to test things.

[Bug 1759836] Re: systemd-udevd consumes 100% of CPU
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) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759836 Title: systemd-udevd consumes 100% of CPU To manage notifications about this bug go to: https://bugs.launchpad.net/bluez/+bug/1759836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
