** Description changed:

- 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

- 
- 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:
