For anyone finding this the problem has re-appeared with Ubuntu 20.04 on a Fujitsu Lifebook A544 after upgrading to BIOS version 1.24 (or 1.25). It shows itself as workers kacpid and acpid_notify hogging most of a core. the fix (or workaround?) is to run sudo sh -c 'echo "disable" > /sys/firmware/acpi/interrupts/gpe13' which works until a reboot, or to make it persistent add to the root crontab (using sudo crontab -e) @reboot echo "disable" > /sys/firmware/acpi/interrupts/gpe13
Whether this has any side effects I don't know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887793 Title: [HP 6710b] Kworker constantly taking about 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
