I have tested with upstream systemtap-3.0-22001, it works just fine.
== Comment: #5 - Naveen N. Rao - 2016-03-08 08:32:25 ==
This is due to systemtap 2.9 not supporting v4.4 kernel. Since systemtap 3.0 is
not out yet, at the least, we will need to backport commits
3f040971e7efb4d323fcb63d83b4337f355c60db,
2736131dfe0aa562d62ffa7f12886e544b7f0eb0 and perhaps
dfb5f085c90cad2f3c61dfb9b17d82006cb02c24 for this to work.
== Comment: #9 - Hemant K. Shaw - 2016-04-05 09:34:13 ==
There is another problem with systemtap 2.9/0.165, Debian version 2.9-2ubuntu2.
# ./stap --all-modules -e 'probe timer.profile {print_stack(backtrace());
exit()}'
