Hello,
I have a logitech , and am having problems with this driver since it is
integrated in the kernel (I used to use svn-builds before this). Here is
the call-trace when trying to use cheese (gnome program):
cheese: page allocation failure. order:5,
mode:0x4
Pid: 11446, comm: cheese Not tainted 2.6.26-ARCH

I saw that someone else also had this problem. I have an Logitech
Ultravision webcam, amd X2 4400, 1 Gig memory and am running in
64-bit-mode. The motherboard is an msi k9a platinum. I'm running kernel
2.6.26 (archlinux).
Thank you and kind regards,
Michel
P.S.: Does anyone know a good video-chat-prgram for linux? I have this
nice webcam (when the driver, ... works), but no program that supports
decent resolutions for video-chat ...
