Re: Runtime probe example causes oops

os_timer was written by Charles. I hadn't really looked at it. It
works fine on my Pentium M running RHEL4 with the latest patches. Well,
it doesn't crash but the data it collects is not right. I'm a bit
concerned that the oops shows it was in the runtime, but I cannot see
how it could have crashed at that particular point. Do you always get
the Oops? If so, could you try putting some printks in
_stp_symbol_sprint() in sym.c? The Oops says
_stp_symbol_print() called kallsyms_lookup() and that is where it
crashed.

I also tried the other probes under the probes directory and had same results. I am going to do what you suggest to figure out what is going on.

Thanks, Hien.
