I confirm the problem. A safe bet is that https://lkml.org/lkml/2016/1/11/587 is the cause. You can verify that /proc/sys/kernel/perf_event_paranoid contains "3". By running echo 2 | sudo tee /proc/sys/kernel/perf_event_paranoid you should be able to use tiptop as a normal user again. I doubt that we can switch the default value in Debian kernels to "2", so I have to say that simply the tiptop website is not up-to-date, at least with respect to the Debian kernels (but also likely to other distributions as well). I'm CCing Ben to let him comment on this. Cheers, Tomasz
