[Bug 66033] quickcam driver causes kernel oops (Edgy)

Sat Oct 14 00:04:19 UTC 2006

Public bug reported:

Binary package hint: linux-source

I have a Logitech "Quickcam for Notebooks" (USB device ID 046d:0870). This uses the quickcam driver. It works perfectly well in Dapper but causes a nasty crash when trying to use it in Edgy.

I should add that I'm using AMD64 -- I haven't got an i386 Edgy install
to try this on.

The bug can be reproduced by attempting to use the webcam in any way
whatsoever that I have found -- Ekiga and Kopete both give the same
result. Attempting to set up a simple GStreamer pipeline to display the
webcam on screen gives:

$ gst-launch-0.10 v4lsrc device=/dev/video1 ! decodebin ! xvimagesink
Setting pipeline to PAUSED ...
Caught interrupt --

Please could you look into this as I think it's a serious regression
from Dapper. If you need any more info, please let me know.
