I'm running a modified -1303 kernel with great success except for one thing: - while trying to compile out of tree DRM for VIA CLE266 from CVS sources I keep getting the following error My system is a FC3 which was yum upgraded to FC4 test 4 and kernel upgraded (along with other applications) since. The unichrome people tell me I have kernel header problems. Can some kind person please help me debug this?
