Hello. I've tried to force load compiled module and got another error: $ sudo modprobe -f agrmodem FATAL: Error inserting agrmodem (/lib/modules/2.6.35-25-generic/updates/dkms/agrmodem.ko): Invalid module format I read in the archive that this error could appear when kernel an module compiled by different compilers, but it looks like versions are the same: $ cat /proc/version Linux version 2.6.35-25-generic (buildd@roseapple) (gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5) ) #43-Ubuntu SMP Thu Jan 6 22:25:16 UTC 2011 $ gcc --version gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5 Copyright (C) 2010 Free Software Foundation, Inc.
