Just to do a bit trial and error routine i added acpi=off to /etc/default/grub. The result was as expected that cpu was running at highest speed and as a change the fan decided to do the same at 84°C. If not for cpu frequency i would have appreciated the improved speed. This is what i found in /proc/acpi/thermal_zone/CPUZ/trip_points
critical (S5): 108 C passive: 100 C: tc1=1 tc2=2 tsp=100 devices=CPU0 CPU1 C002 C003 active[0]: 92 C: devices=FAN0 active[1]: 84 C: devices=FAN1 active[2]: 75 C: devices=FAN2 active[3]: 57 C: devices=FAN3 active[4]: 48 C: devices=FAN4 I haven't seen 57°C for months, but know that a routine uses hwmon values as default trip points with fan speeds designed for lowest temperature, but where ever i look everything seems to be fine except that fan resumes to lowest speed after reaching 70°C and believe me it is hot. Does ANYBODY know which routine should set up fan speeds. It should be something that picks first trip_points and then puts hwmon values above or overrides trip point in favour of hwmon values. Where ever i bend it comes down to hwmon values mixed with trip_ponts. funny thing is that it starts with hwmon value 70°C getting faster at 75 and 84°C omitting 92°C trip-point and emergency shut-down at 95°C. Nice mix and not to mention that all Ubuntu distros seem to have similar problems. It is not the Bios It is not lm-sensors related it has to be a setup routine it needs to poll hwmon and fan trip ponts the mistake has to come to life after hwmon is defined and Linuxtherm: is loaded dmesg acpi device:01: registered as cooling_device7 ??? /sys/bus/acpi/devices/device:01/thermal_cooling/subsystem/cooling_device7/ cur_state = 6 max_state = 24 type = LCD ????? It is not a cooling device but let me guess the adjustment for my LCD screen registered as cooling device 7 (at least cur_state changes after altering screen) M.Peters ANYBODY is this the bug or am i on the wrong trail -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/960925 Title: cpu resources divided to graphic driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpid/+bug/960925/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
