the same patch/commit), kindly add following tags

Hi Oliver,

It looks the direct reason causing the test case failure is the "0" sampled
IP. This is expected. The commit 166f10836a653dfa280d4335603b52f685b8b1ef
("perf/core: Fix kernel register info leak via hardware skid") mitigates a
security hole and may lead to the sampled IP could be 0. 

What user right is used to run this command, root or normal user? If it's a
root user, suppose it should not generate such kind of error. Could you
please add "-vvv" option and rerun this test? The "-vvv" option would print
more  verbose log.

Thanks!

-Dapeng
