Hello Everybody, I hope this is the right place for bugs - if it is one... I'm more a Linux user than hacker. I just upgraded my T60 from some old Ubuntu from ~2016 to the newest release and found out that the fan is really quiet --- and the thing is overheating under load (crashing). When I read the rpm in auto mode the fan is around 3500 rpm even for high thermal sensor values. When I control it manually to 7 it hardly reaches 4000rpm. In disengaged it slowly increases until the watchdog restores the value. I remember that before the update the fan was more noisy and somewhere I found that it should reach higher rpms. Is this a bug in this kernel module, or do I need to search somewhere else? Some terminal outputs: leo@leo-ThinkPad-T60:/proc/acpi/ibm$ cat fan thermal status: enabled speed: 3511 level: auto commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) temperatures: 72 48 44 -128 50 -128 35 -128 55 55 62 -128 -128 -128 -128 -128 leo@leo-ThinkPad-T60:/proc/acpi/ibm$ echo level 7 > fan leo@leo-ThinkPad-T60:/proc/acpi/ibm$ cat fan thermal status: enabled speed: 3936 level: 7 commands: level <level> (<level> is 0-7, auto, disengaged, full-speed) commands: enable, disable commands: watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds)) temperatures: 67 48 43 -128 50 -128 35 -128 55 55 61 -128 -128 -128 -128 -128 Would be great if someone could check that.. Under these circumstances my T60 is going to be toasted soon :( Thanks & Best Regards leo -- http://leo.j-crew.de _______________________________________________ ibm-acpi-devel mailing list ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ibm-acpi-devel
