Comment # 2 on bug 967490 from Thomas Mitterfellner

The light turns on shortly when I power up the laptop but then turns off again.
It turns on again shortly after choosing to boot openSUSE. It still happens
with kernel 4.1.18-8.gb9ac3b9-default.

When I use the camera in skype, e.g. when I go to the video configuration, the
light is on, but as soon as I close that options dialog, the light turns off.
It seems that skype set the camera to a sane state again.

One strange thing is that 2-3 times already the /dev/video0 device just
disappeared. Unfortunately, I could not yet find out how to trigger this (I
just remember using v4l2-ctl to display some info about the camera in one case.
I do not know how to get /dev/video0 back in such a case - do you?

I'll attach the dmesg output and the hwinfo output, just in case.
