I am writing a simple character device driver on a 2.6.4.52 suse 9.1 kernel. It does not do much; basically just initialises the module, runs a few checks and then exits the module. When I try to insert the module, I get the following error: # insmod ./chardriver.ko #insmod: error inserting './chardriver.ko': -1 Invalid module format Now, here is the deal: My kernel build is for the same version that 'modinfo chardriver.ko' gives me. Also, I copied over /boot/config-2.6.4-52-default to /usr/src/linux-2.6.4-52-default/.config. /lib/modules/2.6.4-52-default/build/include/linux/version.h defines my version as #define UTS_RELEASE "2.6.4-52-default" which is what I get with modinfo chardriver.ko What am I doing wrong?
