Hey, I installed 8.0 release and used it very briefly until updating through cvsup to the latest stable source. I had no problems with the release (DVD) version, except that my wireless card wasn't detected, so updating was the natural thing to do. My hardware is an ASUS dual Turion laptop (K50AB), and my working setup was like this: - /boot/loader.conf: cpufreq_load="YES" hint.acpi_throttle.0.disabled="1" - /etc/rc.conf: powerd_enable="YES" It was working fine, the CPU frequency was scaling as expected, I checked it numerous times while working and idle with 'sysctl dev.cpu.0.freq'. Also, the load was displayed correctly in the taskmanager (I don't remember what was displayed in 'top', but I suppose it was ok). Now, after updating through buildworld, powerd doesn't scale the frequency anymore. My observations pointed out that the problem is that the CPU load is not detected correctly anymore: - I got three frequency steps: 575, 1150 and 2300 (correctly detected by dev.cpu.0.freq_levels while cpufreq module is loaded), but powerd scales down the frequency to the minimum, 575 then keeps it like that no matter of the load - dev.cpu.0.freq shows 575 and I got large build times because of it. To be able to use it fully, I have to kill powerd and set the frequency manually, or disable it at startup. - 'top -P' displays only one CPU and its load is 0% everything all the time, despite any load - I can't see anything in a taskmanager, the last time I tried with xfce and CURRENT (CURRENT had the same issue) - dev.cpu.0.cx_usage shows 100%. --- I'd like to find out the problem, why the CPU level is not detected correctly and how to fix this/report. Thanks, Mihai
