https://bugzilla.novell.com/show_bug.cgi?id=231107 ------- Comment #21 from f.alabas@ttnet.net.tr 2007-02-08 18:00 MST ------- :-( still have the same problem. With full load on CPU, (un)plug AC does not have any effect on processor speed. In both case,the output of "watch -n1 cat /sys/devices/system/cpu/cpu0/cpufreq/{scaling_max_freq,scaling_cur_freq}" 1600000 1600000 The processor works under passive cooling limit as output of cat /proc/acpi/thermal_zone/THRM/temperature when idle temperature= ~45 when full load temp= ~60 and output of cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 105 C passive: 93 C: tc1=2 tc2=3 tsp=100 devices=0xffff810037ed7a10 I have also checked the files of /proc/acpi/ac_adapter/ACAD/state /proc/acpi/battery/BAT1/state and they show the correct status in response to AC plug/unplug conditions. As a reminder from bug opening, the problem exists only if I boot the machine when AC unplugged. Then plugging in the AC does not tell the processor to reach highest available frequency which is the above story. However, when I boot the machine with AC plugged, system works ok. AC-plugged under full load the output of "watch -n1 cat /sys/devices/system/cpu/cpu0/cpufreq/{scaling_max_freq,scaling_cur_freq}" 1800000 1800000 and when AC-unplugged the output is 1600000 1600000 then plugging again 1800000 1800000 The viewpoint is; while boot on AC, BIOS and Kernel coordinates, so no problem happens; but while boot on Battery, BIOS and Kernel lost the coordination, so either BIOS does not send whatever the necessary signal to Kernel or Kernel does not grant whatever the signal BIOS send. So something works strange if the machine boots on battery although all acpi-related events and values in the acpi-related files react well. One more thing; although there is no information about "powering type at boot", the most similar issue to my case had been reported for a HP nx6125 laptop. Interestingly, that machine that I know well is the twin brother of mine. i.e. same cpu (except L2 cache size), same chipset etc... I noted some other, maybe unusual thing in the file /sys/devices/system/cpu/cpu0/cpufreq/ondemand/ignore_nice_load When boot on battery its value is 1, then AC plugged its value is 0. When boot on AC plugged its value is 0, then AC unplugged its value is still 0. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
