I never had any glitches but there have been indeed a few of unexpected reboots in the last days.
Well, not exactly complete reboots, more a restart of some services I guess:
From watching TV, out of nowhere, a black screen appears and after a few seconds I'm on the LE main screen.
Plus I had a couple of picture blackouts the last days. From watching TV, a black screen for a second or two and then back to the TV program as if there was nothing.
Not sure if this fits your issue titoasi but I'll try do dig deeper into it as soon as I find time and post the logs link here.
