I have the exact same problem, also a Dell computer (Inspiron something). CPU load is almost always at 100% and temperature sensors measure over 100C! My computer has become unusable.
Also seeing a lot of these: CPU1: Core temperature above threshold, cpu clock throttled (total events = 2738) Curious if this bug is a duplicate of https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1759836 (it didn't include syslog/journal so I can't know for sure) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767968 Title: systemd-udev cause high cpu load after upgrade to bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1767968/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
