Fresh install of ubuntu 14.04 on a touchscreen Toshiba Satellite laptop with intel graphics. I tried to follow the fix here:

Why does kworker cpu usage get so high?

It didn't work; my problem seems to be on gpe10, which lists as follows:

/sys/firmware/acpi/interrupts/gpe10:11042017   enabled

This only takes up about 32% of one of my cpus (there are 4 available), but it shouldn't be running that high and I want it gone. As stated, the fix above didn't work; after reboot, nothing happened. I even tried running crontab as root, but that did nothing.

Ok, I think I solved the problem. I'm going to leave my previous non-answer in place because I believe it has useful information. Or at the very least it has keywords which will help people find this answer.

The problem was that noclobber was set in rc.local, so it wouldn't add disable to gpe10. I solved that by adding two lines to rc.local. Issue the command:

sudo gedit /etc/rc.local

And then append the following two lines BEFORE the "exit 0" line:

set +o noclobber
echo "disable" > /sys/firmware/acpi/interrupts/gpe10

Hope that helps someone.
