Are you running the 2.6.35-rc5 kernel? If you run modinfo on the module, look for the vermagic string. You can get most of the information about the kernel that you're running by using cat /proc/version The kernel version, compiler version and stuff like SMP, PREEMPT 4KSTACKS etc all have to match with the vermagic info from your module. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
