Bug Description
My X1Carbon becomes quite laggy, the cursor hangs for a few seconds and then resumes while my system is compiling some code, or lets says PyCharm is indexing things or Android Studio is compiling some code. I was using 4.4 on Xenial a few days ago and everything was working just fine. Installed Yakkety and this issue happens.
TEST CASE:
`stress -c 4` <-- that results in system slowness.
I will downgrade the kernel and see if that mitigates the issue.
