https://bugzilla.kernel.org/show_bug.cgi?id=74551 --- Comment #11 from maxis11 <ya.maxis11@xxxxxxxxx> --- 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. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
