@mike: > if you don't think this is the right bug I can open another one or something,
This is not the right bug report, and we need to get off it before others start to complain. However, it isn't time to open a new one yet, in my opinion, because we don't yet know what to file it against. > but unless you can suggest a patch to try or a setting to change I am > probably just going to disable pstate on the GRUB command line and be done > with it Well, a lot of people do just that, but then also wonder why issues don't get solved. Issues don't get solved if people don't investigate. Myself, and without any proof, I suspect thermald is your root issue. Have a look at this bug: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1656528 By the way, a cool trick for some of the stuff you were listing above is to do this instead: root@s15:/sys/devices/system/cpu/cpu0/cpufreq# grep . * affected_cpus:0 cpuinfo_cur_freq:1599768 cpuinfo_max_freq:3800000 cpuinfo_min_freq:1600000 cpuinfo_transition_latency:4294967295 related_cpus:0 scaling_available_governors:performance powersave scaling_cur_freq:1599768 scaling_driver:intel_pstate scaling_governor:powersave scaling_max_freq:3800000 scaling_min_freq:1600000 scaling_setspeed:<unsupported> -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1188647 Title: Please change intel_pstate default to disable Status in linux package in Ubuntu: Fix Released Bug description: 3.9 introduced a new default governor on SandyBridge CPUs called INTEL_PSTATE which, when built in and enabled (the default), removes all other governors (like our usual default, ondemand). 3.10 extended this to Ivybridge generation CPUs. In theory, this isn't an awful thing, as the new Intel pstate governor should be higher performance and give better power savings. In theory. In practice, it drives my CPUs to max frequency nearly constantly, spins my fans like mad and, somehow, does all of this while also eating enough CPU time in kernel threads to make my machine choppy, unresponsive, and unable to do simple things like play videos when I get off work. Therefore, I propose that we, for now, toggle intel_pstate to disable by default (I am using intel_pstate=disable on my command line right now, with great success), so it's still built in, and people can play with it, but it's off by default.
