Description of problem: I believe this is a kernel 4.3.x regression - it was working alright with 4.2.x. # acpi -V Battery 0: Discharging, 92%, 01:09:34 remaining Battery 0: design capacity 3000 mAh, last full capacity 1142 mAh = 38% Adapter 0: off-line No support for device type: thermal No support for device type: thermal and I have floods of messages in /var/log/messages about: gnome-shell.desktop: Gjs-Message: JS LOG: error reading: /sys/devices/virtual/thermal/cooling_device0/cur_state /sys/devices/virtual/thermal does not exist, although I have: # find /sys/ -type f -name '*temp*' /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 /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon1/temp1_crit /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon1/temp1_crit_hyst /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon1/temp1_input /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon1/temp1_max /sys/kernel/debug/kvm/halt_attempted_poll I think I have at least two temperature sensors on this hardware. Version-Release number of selected component (if applicable): kernel-4.3.3-301.fc23.x86_64 kernel-4.3.3-303.fc23.x86_64 kernel-4.3.4-300.fc23.x86_64 How reproducible: Always since upgraded to kernel 4.3.x from 4.2.x, I think. Steps to Reproduce: 1. use kernel 4.3.x, run "acpi -V" , or look for /sys/devices/virtual/thermal 2. 3. Actual results: 'acpi -V' shows: No support for device type: thermal No support for device type: thermal Expected results: 'acpi -V' should tell me the temperatures from the sensors. Additional info:
Upgrading to 4.4.2 seems to have cured it. # rpm -q kernel kernel-4.3.4-300.fc23.x86_64 kernel-4.3.5-300.fc23.x86_64 kernel-4.4.2-300.fc23.x86_64 # uname -a Linux localhost.localdomain 4.4.2-300.fc23.x86_64 #1 SMP Fri Feb 19 15:40:11 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux # acpi -V Battery 0: Discharging, 95%, 01:15:56 remaining Battery 0: design capacity 3000 mAh, last full capacity 1142 mAh = 38% Adapter 0: off-line Cooling 0: Processor 0 of 10 Cooling 1: Processor 0 of 10 Cooling 2: Processor 0 of 10 Cooling 3: Processor 0 of 10 # sensors radeon-pci-0008 Adapter: PCI adapter temp1: +56.0°C (crit = +120.0°C, hyst = +90.0°C) k10temp-pci-00c3 Adapter: PCI adapter temp1: +55.4°C (high = +70.0°C) (crit = +115.5°C, hyst = +108.0°C) fam15h_power-pci-00c4 Adapter: PCI adapter power1: N/A (crit = 14.98 W) # ls -l /sys/devices/virtual/thermal total 0 drwxr-xr-x. 3 root root 0 Feb 26 05:52 cooling_device0 drwxr-xr-x. 3 root root 0 Feb 26 05:52 cooling_device1 drwxr-xr-x. 3 root root 0 Feb 26 05:52 cooling_device2 drwxr-xr-x. 3 root root 0 Feb 26 05:52 cooling_device3 would be nice to know what broke and what fixed, but otherwise this can close as CURRENTRELEASE .
