--- Comment #11 from maxis11 <ya.maxis11@yandex.ru> ---
executing "echo OFF > /sys/kernel/debug/vgaswitcheroo/switch" on every kernel
causes freezing OS(even where runpm and dpm are working). Additionally, when OS
freezes, it doesn't write any log(not in kern.log or Xorg log) and doesn't
executing any commands (try to add after previous command && dmesg > info.log,
but file wasn't created), so I just can't give you any log. Problem still
exists in 3.15.5 and in 3.16.0-4-generic.
