Hi,
I have an ASUS A8JP Notebook with a build in webcam and I am using Ubuntu
12.04. The camera is working nice with Cheese and kernels before 3.2. I have
tested the following once 2.6.32.61, 2.6.33.20, 2.6.34.11, 2.6.35.14, 2.6.36.4,
2.6.37.6, 2.6.38.8, 2.6.39.4, 3.0.94, 3.1.10. In all later kernels I have
tested (3.2.50, 3.4.60, 3.10.10, 3.11.0, 3.12.0-rc1) Cheese shows for some
seconds a green and noisy image and crashes then with a segmentation fault.
Hans de Goede supposed that the error is caused by usb sub-system because of
the errorlogs
The error logs are just a hint in the direction of this being an usb (hcd
driver?) problem,
my main reason for thinking that this is likely an usb problem is that the
webcam driver
was not changed between 3.1 and 3.2, which is where the regression occurred.

I hope this help to resolve the problem.
