Comment # 4 on bug 76998 from tcl_de@gmx.net

I did a small "bisection" and installed the 3.9.0-030900-generic,
3.10.0-031000-generic and 3.14.0-031400-generic kernels from the Ubuntu
MainlineBuilds.

3.9 works, 3.10 and 3.14 hang.

The attached logs are for the 3.9 kernel.

I'm sorry, I prefer not to do a git bisect because I can only spend a limited
amount of time on this bug.
