yes, this kernel boots fine: Linux 3.18.0-031800rc1-generic

The backlight issue works much better now.
One thing I noticed is that when I redock the laptop, the backlight goes off. Increasing the backlight via the Fn+F9 key does not work immediately. It takes a few seconds before it accepts new controls.  This might, however, be caused by some scripts which react to the laptop being docked <https://github.com/martin-ueding/thinkpad-scripts/>. I thought I removed them, but maybe there are still traces.

Anyway, I received this, which may be relevant:

Given that it works better, I'm adding the  kernel-fixed-upstream-3.18-rc1 tag
