https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227388 Bug ID: 227388 Summary: [cpufreq] [patch] Most newer Pentium M ULV frequency tables doesn't finished correctly Product: Base System Version: 11.1-STABLE Hardware: i386 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: xdelta@meta.ua Created attachment 192359 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=192359&action=edit est.c patch I've installed FreeBSD 11.1 onto Fujitsu Siemens P7120 with Pentium M 753 ULV 1.2GHz inside. In result: system refused to run powerd, sometime system crashes (mostly after executing "reboot" or "sysctl -a"), messages "tsc_levels_changed: no max freq found" and "cpufreq: need to increase CF_MAX_LEVELS" are appeared on console. "sysctl dev.est.0.freq_settings" output: dev.est.0.freq_settings: 1200/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 1200/-1 11 00/-1 1000/-1 900/-1 800/-1 600/-1 1200/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 1200/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 1200/-1 1100/-1 1000/-1 900/-1 800/ -1 600/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 1100/-1 1000/-1 900/-1 800/-1 600 /-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 11 00/-1 1000/-1 900/-1 800/-1 600/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 1100/-1 1000/-1 900/-1 800/-1 600/-1 As turned out, some frequency tables, including one for "Pentium M 753 ULV 1.2GHz" have no finalization line "FREQ_INFO( 0, 0, 1)". After applying patch - all mentioned symptomps are disappeared. -- You are receiving this mail because: You are the assignee for the bug.
