IMHO, quite likely the message you saw happened since you compile the kernel module with different version of gcc and/or different gcc parameter, that somehow yield binary incompatibility. Another thought, what arch do you use when you compile that kernel module? AMD Geode too? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
