https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202651 Bug ID: 202651 Summary: cpufreq no longer works in 10.2 on Intel D525MWV Product: Base System Version: 10.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: viktor.stujber@gmail.com After updating from 10.1-RELENG (2014-12-07) to 10.2-RELEASE, I can no longer manage the CPU's frequency. kernel: Starting powerd. kernel: powerd: no cpufreq(4) support -- aborting: No such file or directory This is the consequence of sysctls 'dev.cpu.X.freq' and 'dev.cpu.X.freq_levels' not being registered, indicating a problem with the 'cpufreq' module. I built/installed a clean GENERIC kernel and all available modules, but the problem still persists. I tried setting sysctl debug.cpufreq.verbose=1, which according to sys/kern/kern_cpu.c activates CF_DEBUG() calls. But the message in cpufreq_attach(), that should say "cpufreq: initializing %s", does not show up. I don't know if this means that the module doesn't even try to load. Help would be appreciated. -- You are receiving this mail because: You are the assignee for the bug.
