and the timer.stp script is:

probe kernel.function("timer_interrupt")
{
printf("Called %s\n", probefunc());
print_backtrace();
}

####probe timer.ms(10000) { exit () }

probe end {
        printf("\nDONE\n")
}

Can someone help me out with the "debuginfo" file availability on Ubuntu?

I did a grep:

uname -r
2.6.28-17-generic

grep -i debug_info /boot/config-2.6.28-17-generic
CONFIG_DEBUG_INFO=y

And the current kernel (as apt-get updated, not custom compiled by me)
did compiled with DEBUG INFO.
