Bug Description

System Information:

Dell XPS13 developer edition (the extremely high res touch screen version)
Ubuntu 15.04
latest kernel (3.19.0-20-generic from 29th May)

Symptoms:

Intermittently, when using the OS normally, a key (often lightly pressed) will keep typing its letter (or deleting, or whatever) after I've stopped pressing it. I haven't noticed it with any particular key; it seems to happen when I am engrossed in typing something and I hit a key lightly. I am able to reproduce it, in fact, by pressing the key lightly myself.

Actions:

I am happy to investigate this issue further, with a few pointers from people:

Anyone familiar with the USB keyboard protocol, or the way the events are propagated in the kernel, would be very helpful in finding out how to debug this issue. If there is a solution as simple as a kernel argument, I will be delighted!
