I also observed in my Dell laptop similar to Szymon that it relates to Touchpad.
My workarounds- Soon after booting, stopping and starting systed-udev eliminates all bind and unbind problems and response drastically improves. I used the following commands in sequence- 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 My understanding- Before all hardware is discovered properly, bind/unbind start executing when no procedures are available and does not get reinitialized. After stopping and starting, it gets all the procedures in place. Probably, it is booting sequence problem. -- 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/kernel/+bug/1759836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
