Re: register_kprobe undefined symbol on 2.6.11 of X86_64

Jim,

Thanks. It seems your way solve such "unknown symbol" problem. But the
system is stuck when I insert the module, this is the reason why I send
you response a little bit late, reboot twice. : )

Currently, I am monitoring the do_fork function. Is it too sensitive to
be monitored? When I get rid of the function address of the kp,
everything is OK.

BTW, how can I remove that module? rmmod cannot work?

Thanks,
Neo

I would remember that if researchers were not ambitious 
probably today we haven't the technology we are using!
