Hi,
I tested systemtap with latest Ubuntu.
Systemtap was not able to find kernel debuginfo ,only this is fixed and the
make check error and other failures needs to be fixed yet.
systemtap-2.9# stap -ve 'probe kernel.function("_do_fork") { printf("hit\n"); }'

It looks like there is a mismatch between the kernel and the systemtap
version. Need to upgrade systemtap. For ubuntu 14.04.03, systemtap 2.3
worked because it has a older kernel and older systemtap. Its no more
the case now. The systemtap version needs to be upgraded.
