Public bug reported:
Samsung notebook: NP350E5C-A02AU
FN+F6 (Mute), FN+F7 (Volume Down), and FN+F7 (Volume Up) cause the
machine to become highly unstable requiring a power off holding the
power button in.
This did NOT happen in Ubuntu 13.04 so I conclude that it is a hardware
issue under newer kernels (one of many issues, all being reported
individually).
