Can you give the v4.8-rc1 kernel a try? It can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8
We can perform a kernel bisect, once we know the last good kernel and
first bad one.

Title:
X1Carbon comes to a crawl during high CPU usage tasks
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Yakkety:
In Progress
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.
I will downgrade the kernel and see if that mitigates the issue.
