Sicco van Sas, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  0ac8:c002 [Sony VAIO VGN-FE21M] Green/garbled/black webcam [0x0ac8
  0xc002] output

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm running Ubuntu 12.04.2 32bit and the webcam [0x0ac8 0xc002] of my
  Sony VGN-FE21M laptop gives green/garbled/black output when trying to
  use it in cheese, xawtv, vlc or skype. The suggested solutions in
  https://help.ubuntu.com/community/Webcam/Troubleshooting don't work.

  The output in the terminal when running 'xawtv' (see the attachment for a screenshot):
  v4l2: ioctl(fildes = 5 "/dev/video0", request = VIDIOC_QBUF, struct v4l2_buffer *data = { index = 0, type = V4L2_BUF_TYPE_VIDEO_CAPTURE, bytesused = 9682, flags = V4L2_BUF_FLAG_QUEUED, field = V4L2_FIELD_NONE, timestamp = { 18637,563 seconds }, timecode = { type = 0, flags = 0, frames = 0, seconds = 0, minutes = 0, hours = 0 }, sequence = 0, memory = V4L2_MEMORY_MMAP, m.offset = 2882400000, length = 16777216, input = 0 }) failed, Ongeldig argument (22, EINVAL) because the frame buffer is already in use

  The output in the terminal when running 'vlc v4l2:///dev/video0':
  [0xb53ed7a8] v4l2 demux error: Failed to unlock (VIDIOC_QBUF)
