Skylake install, dmesg being flooded by ACPI exceptions. Causes cpu core to be overworked and uses up space for log quite quickly.

This then is a temporary fix for kernel Bug 105491 and 53071 show signs of change.

Ultimately appears to be a BIOS issue, but I've no idea beyond those two bug reports and the above 'tweak'.

Since Linux 4.10, you need to use the keyword "mask" instead of "disable":

echo "mask" > /sys/firmware/acpi/interrupts/gpe6F
