When running many of the stap scripts, it blocked here as above.  What
are the possible reason?   This is git-updated up to latest.
(8a49d1d23c77033bf98fc7b139b37f83e3e0eb49).

This blocked:

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

I just have a quick test, the above script works fine in my x86_64 box(2.6.25-rc5).
Could you provide more info about your environment and verbose output?


Best regards,
Wenji
