Ignore previous comment (I pasted sles result by mistake)...
On ubuntu again I did run 
strace -e open stap --vp 09 -e 'probe kernel.function("sys_open") {log("hello
world") exit()}' |& grep vmlinu

-----------------------------------------
I tried crating link 

 root@ubuntu:~#  ls -l /usr/lib/debug/boot/vmlinux-3.16.0-23-generic.debug
 lrwxrwxrwx 1 root root 45 Nov 10 03:35
/usr/lib/debug/boot/vmlinux-3.16.0-23-generic.debug ->
/usr/lib/debug/boot/vmlinux-3.16.0-23-generic

Then did try to run stap again 

#stap -v -e  'probe kernel.function("sys_open") {log("hello world") exit()}'
