I tried all steps as described in a similar bug 815134.
Comment 2 Hans de Goede 2012-06-25 05:21:24 EDT
Since this happens with other v4l2 apps then cheese, it likely is a kernel bug, changing component.

The OS installed on HDD is i686 architecture.
I just tried LiveOS x86_64 architecture with the following results

stock LiveOS F17 (x86_64 no updates)
 when i run cheese from terminal nothing happens no window opens. I got whole bunch of GTK error messages, but the system doesn't hang. CTRL+C returns back to prompt. No light on the camera comes up.

updated cheese and gstreamer-plugins
 ran "yum update --enablerepo=updates-testing cheese gstreamer*"
 run cheese from terminal --> system hangs

Is this still happening with 3.6.9 kernels?
Comment 5 Frank 2012-12-10 04:12:08 EST
Hi Justin,

just tested with 3.6.9 kernel and the camera appears to be working now. 

Cheese is working fine. 
Camorama is wirking fine.
Skype - camera doesn't show preview in Skype setting. However video calling IS working. It is probably an issue with Skype though.

I believe the bug can be closed.

Thank you
