Hi Mark,

I admit that current workaround is a little annoying. But we need to 
wait utrace update. In fact, "stap -c" will cause kernel panic even on 
2.6.27+latest utrace. One simplest way is to change BUG_ON to WARN_ON so 
that no kernel panic come up any more. I think the commit will be 
reverted once new utrace kernel is ready.

Regards,
