Hi all, My laptop camera stopped working recently, I presume when I upgraded to kernel version 2.6.25. I then tried 2.6.26 with the integrated uvc driver, but with the same result; the camera LED flashes twice during boot (udev and hald), yet it doesn't work in e.g. skype. Tested the current version in gentoo stable (233?) and svn.
