It is also reporting that the fan is stoppend (tachometer reads 0) -- assuming it can actually read the tachometer in your computer. > "fan" module is not loaded during boot (!) > Manually loading creates nothing more than: > > /sys/module/fan/drivers/platform:acpi-fan > [and nothing specific inside dmesg] Hmm, that *is* bad. And your prime suspect. > Maybe related to this line in dmesg? > > [drm] Internal thermal controller without fan control No, that just means your GPU does not have its own fan, which is expected since this is a notebook. > # find /sys -regextype posix-egrep -regex '.*(cool|fan|temp)[^/]*' > /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon2/temp1_max > /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon2/temp1_crit > /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon2/temp1_crit_hyst > /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon2/temp1_input > /sys/devices/pci0000:00/0000:00:01.0/hwmon/hwmon0/temp1_crit > /sys/devices/pci0000:00/0000:00:01.0/hwmon/hwmon0/temp1_crit_hyst > /sys/devices/pci0000:00/0000:00:01.0/hwmon/hwmon0/temp1_input Looks like chipset thermometers... but not cooling devices. Can you send me the DSDT and XSDTs? You'll need a recent version of acpidump to extract them. Binary format (compressed) is fine, I can run them through iasl (the ACPI AML disassembler) myself. -- Henrique Holschuh ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ ibm-acpi-devel mailing list ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/ibm-acpi-devel
