2014-12-18 09:24:43 Jussi Pakkanen summary Kworker takes 100% CPU when booting with efi Kworker takes 100% CPU after installing OSX Yosemite upgrade
2014-12-18 09:25:16 Jussi Pakkanen description When running on a Macbook Pro Retina that has been booted with EFI, a kworker process constantly takes 100% CPU. If you boot in legacy mode this does not happen. When grepping for large values in /sys/firmware/acpi/interrupts, this one stands out: /sys/firmware/acpi/interrupts/gpe66: 2510732 enabled Trying to disable it with echo disable > /sys/firmware/acpi/interrupts/gpe66 makes the CPU load go away. This will also prevent installation of Ubuntu, because if you try to install when kworker is running causes ubiquity to hang while trying to format the disk.
