Hello there, I've found the solution to my problem (apparently at least). I downloaded a vanilla kernel, instead of the distro kernel, and voil?. It worked. At least, it compiled, but I'm confident :) The kernel was Mandrake 9.1 updated 2.4.21-0.25mdk. Compilation was ok with i2c patch only, but broken with lm-sensors patch. Thanks and all the best :) Romain
