Setting acpi=noirq worked for me after a couple of reboots! I guess my laptop was really hot and need time to cool down. Just to reiterate the workaround:
1. Edit /etc/default/grub 2. Add "acpi=noirq" to the GRUB_CMDLINE_LINUX_DEFAULT line (so it's: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=noirq"). 3. Run sudo update-grub2 4. Shutdown and let laptop cool off if it has been running for a while. 5. Start laptop and run system monitor and top to make sure problem has disappeared. Very happy with my Chronos 7 now :). -- 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: Kworker constantly taking about 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/887793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
