ran tests on m3545035. ubuntu 18.02 with latest updates. Recreated the problem first (Not enough memory for annotating '__irf_end' symbol! and a hang) with perf top and a workload. Installed provided packages, reboot to activate the new kernel:

root@m3545035:~# uname -a
Linux m3545035 4.15.0-55-generic #60+lp1828166.2-Ubuntu SMP Fri Jul 12 12:49:26 UTC 2019 s390x s390x s390x GNU/Linux

ran perf top again and could still recreate the problem: Not enough memory for annotating '__irf_end' symbol! and a hang.

What I see: perf -v gives me 4.15.18 before and after linux-tools* install. Is that expected? The perf fixes do not come with a new version of perf?
