Title: Problems with gpe06 interrupt storm on a 2016 Macbook Pro Status in linux package in Ubuntu: Incomplete Bug description: I also reported this upstream (https://bugzilla.kernel.org/show_bug.cgi?id=117481), just reporting this here so that the upstream fix does not get lost in the noise: Symptoms: - With a freshly installed Ubuntu 16.04 (but also occurs using the live CD/USB) on a 2016 Macbook Pro (hardware version MacBookPro11,2) CPU core is 80-90% pegged with kworker: 12772 root 20 0 0 0 0 R 84,1 0,0 15:37.79 kworker/0:6 - When doing grep . -r /sys/firmware/acpi/interrupts/ I see a lot of interrupts on gpe06: /sys/firmware/acpi/interrupts/gpe06:222309848 enabled - Disabling gpe06 frees up the core without any noticeable side-effects: # echo disable > /sys/firmware/acpi/interrupts/gpe06 I put the above in the root crontab with @reboot which solved the problem for me for now.
