does Linux development include regression tests?

In October I announced that starting with 3.6 kernel it was eventually safe to unplug Zenbook.
Then in bugreport I was told that Sentelic touchpad driver was included in 3.8 kernel.
And guess what… I don’t have to patch kernel to have working touchpad using 3.8 kernels but I have to worry about unplugging laptop cause with 3.8.x kernel it’s quite common that it turns laptop off again.
So the question is… do we have any regression tests in kernel?
Should I test every kernel release between 3.8.5 and 3.6.0 to find the one that incorporated that bug again?
