Description of problem:
After a recent kernel upgrade, I am unable to use an internal webcam in my laptop HP 6730b: usually the first user of /dev/video0 works OK (I am testing with cheese now), but after I close it, the subsequent users of /dev/video0 are getting stuck in the D state (I am not able to kill them, etc.). It worked OK a month ago, and the problem appeared after the recent yum update (most probably the update of kernel).

Version-Release number of selected component (if applicable):
kernel-3.15.7-200.fc20.x86_64
cheese-3.10.2-1.fc20.x86_64

How reproducible:
100 %

Steps to Reproduce:
1. reboot the system, log in
2. run cheese (it displays the video from the internal webcam), close it
3. run cheese again

Actual results:
The second cheese process is stuck in the "D" state.

Expected results:
The second cheese should work the same way as the first one.
