Comment 45 for bug 1506817

In comment #34 you state:
"This leads one to believe there is a user space component to this that stopped allowing 4.5-rc3+ to work for you."

I had not changed anything that would account for this, other than responding to your request for a new kernel.
This activity is described in my comment #21:
"I was running kernel 4.5-rc3 and everything was great. Then sometime around Feb 3, 2016 (I don't know the exact date),
following an standard upgrade from Ubuntu, the old symptoms (left mouse button sticking) returned."

Following that date, nothing I tried would make 4.5-rc3 work, including repeating all the steps in reinstalling 4.5-rc3, from scratch.

The only possibility that I can think of is that a standard weekly ubuntu update to the kernel (headers, modules, etc?) was the source of the change.

I am quite sure that I did not cause this by my tinkering.
