Tarvin [EMAIL > PROTECTED] > http://www.digbyt.com Hi, There seems to exist at least two current kernels - one is the kernel to which /usr/src/linux points, this one is used by most (all ?) kernel-module programs (i have 3 of them: nvidia, arpstar, loop-aes; had also alsa-driver). When you compile/recompile any one of them they use the kernel sources pointed by /usr/src/linux. Patch kernel sources too (e.g. "l7-filter"). The second kernel is your running kernel (available by "uname -r") this one is the one actually running at any givenn time. Don't have any examples of something using this one. Anybody here?
