- The script is the same that is running in the a x86 machine using the same

- Systemtap seems to be working with simple scripts:

$ sudo stap -ve 'probe begin { log("hello world") exit () }'

have a look to https://sourceware.org/bugzilla/show_bug.cgi?id=22572).

Any clue?

I could attach a full (-vv) output and the temporary files (-k) if it is
needed.

Cheers,
