https://bugzilla.kernel.org/show_bug.cgi?id=81701 --- Comment #17 from Oleksandr Natalenko <oleksandr@xxxxxxxxxxxxxx> --- @Ayan: I've put pr_info to cpufreq transition notifiers, and what I can see is that frequency changes often enough (several times per second), so there's no need to do extra CPU load/relax cycles. Also, machine could hang after 2 hours of successful uptime, or after 25 hours, and there's no obvious reason for hang. To answer your question, I've tried your script (stress-testing for several hours), and got nohing as well, but that is not significant result.
