Bug Description

Dell System Inspiron 14 7000 Series 7437

CPU: Intel(R) Core(TM) i7-4500U CPU @ 1.80GHz (4x)
GPU: 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
BiosVersion: X21

HA4-E3-C1 Primax (0bda:5601 , 50-77501WNC8)
HA7-E3-C2 Liteon (0bda:5750, _13P2SF109)

Both of the modules use realtek chipset.

In the 1280x720 resolution only have half image displayed camera preview and still image; in 960x540 resolution camera preview displayed with full black but camera LED is enabled.

Furthermore, camera test "multiple-resolution-images" also failed.
When testing by manually take still images in different resolution, camera will hangs when switch to another resolution.

1. install manifest X08 and boot into OS
2. Run camera test "multiple-resolution-images" which takes multiple pictures based on the resolution supported by the camera and validates their sizze and that they are of a valid format.

Expected results: Test got passed with multiple images successfully taked in each resolution.

Actual results: Can't take still image in each resolution.

Here is the testing linux-image package with #1,#2 patches.

I did few stress test on below test platforms:
HA4-E3-C1 Primax (0bda:5601 , 50-77501WNC8)
HA7-E3-C2 Liteon (0bda:5750, _13P2SF109)

The test platforms work good in the tests:
 preview with resolution change (cheese/guvcview)
 Take photos.
 S3 stress 30 times than preview and take photos.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-quantal' to 'verification-done-quantal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!
