This may not be relevant to the question that you asked. But there are some good debugging techniques like kprobe,jprobe. There are sample programs in the kernel source under the directory samples/kprobes/. Those examples are very easy to understand and are much powerful than using printk. - Thanks, Vikram _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
