I've seen other posts of this problem, but I haven't seen any reasonable attempts to answer or resolve it. After building and installing v4l-dvd-kernel many other modules that require v4l-related modules are broken. I see that you implement your own videodev and such and I can only assume that is were the problem lies. I own two webcams both of which are rendered useless after intalling v4l-dvb. When trying to load either module I get the following error: ~$ sudo modprobe quickcam FATAL: Error inserting quickcam (/lib/modules/2.6.17-10-generic/misc/quickcam.ko): Unknown symbol in module, or unknown parameter (see dmesg) examining the dmesg output shows the following: [17181665.160000] Linux video capture interface: v2.00 [17181665.196000] quickcam: disagrees about version of symbol video_devdata [17181665.196000] quickcam: Unknown symbol video_devdata [17181665.196000] quickcam: disagrees about version of symbol video_unregister_device [17181665.196000] quickcam: Unknown symbol video_unregister_device [17181665.196000] quickcam: disagrees about version of symbol video_register_device [17181665.196000] quickcam: Unknown symbol video_register_device At first glance one would assume that this arose from compilation under a different kernel, but that is not the case. I am aware that this is a known issue, but I have a couple of questions: 1. Is it currently being addressed? 2. Is it known as to where this problem might be coming from?
