Public bug reported:
Keyboard on an LG LW25 laptop is not functional anymore on Ubuntu 13.10.
Any 3.8.x Ubuntu kernel works fine. Starting with 3.9.0, the keyboard
breaks. External keyboards are still fine.
Using i8042.dumbkbd=1 as a kernel boot parameter seems to be a usable
workaround.
A kernel bisect suggests that the first bad commit is:
