https://bugzilla.kernel.org/show_bug.cgi?id=53051 Summary: Conservative governor get's sometimes stuck at highest frequency Product: Power Management Version: 2.5 Kernel Version: 3.6.11 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: cpufreq AssignedTo: cpufreq@xxxxxxxxxxxxxxx ReportedBy: cem.aydin@xxxxxx Regression: No Created an attachment (id=91801) --> (https://bugzilla.kernel.org/attachment.cgi?id=91801) Zipped files as described in description. About once a week, when booting daily, the CPU (all cores) get's stuck at highest frequency. Unfortunately, I can't tell exactly when this appeared but it was about during the time, when I switched to systemd and cpufrequtils got replaced cpupower, about half a year ago. The kernel modules are loaded properly and the start scripts are executed. I can not find any difference, when this occurs or when it doesn't. Exept that the frequency is stucked at highest level of course. When this occurs I wasn't able to set the frequency manually (by the userspace governor). Reloading the conservative module or reexuting the (systemd) start script did not have any effect. The only thing I can do to resolve the issue is reboot. I use an up to date Arch Linux with the regular kernel and systemd. Additional Infos: proc/cpuinfo reports the wrong frequency (lowest). I think this is mentioned in another bug. However cpupower -c all frequency-info (executed as root) reports the correct highest frequency. I can clearly see that this is the true frequency because the temperatures reported by sensors are almost 10°C higher than under normal circumstances. I don't have any process that could cause the governor to raise the frequencies. CPU usage is below 1% and load is between 0.0 and 0.05. Hardware: A HP Pavilion dv6 CORE i5 Attachments: - cpupower (/usr/lib/systemd/scripts/cpupower, the start up scripts used by systemd to set the frequencies) - cpupower.conf (/etc/conf.d/cpupower) - cpupower-service.txt (output from systemctl status cpupower.service) - cpupower.txt (output from cpupower -c all frequency-info) - journal.txt (output from journalctl -b | grep cpufreq) - lsmod.txt (output from lsmod |grep cpufreq) - proc_cpuinfo.txt (output from cat /proc/cpuinfo (wrong frequencies)) Please let me know if you need additional info.
