raxp, the next step is to fully commit bisect from kernel 3.16 to 3.17-rc1 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. After the offending commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your understanding.

Steps to reproduce: 1) Boot into Ubuntu 2) run pm-suspend 3) Wake up the laptop After a few seconds the CPU fan spins up to max speed and it doesn't slow down until reboot/poweroff. Hibernation can also fix this, so, fan runs at normal speed. It is not a PWM fan, so, I guess, I can't control it via /sys. Output of "sensors" before suspend: acpitz-virtual-0 Adapter: Virtual device temp1: +55.0°C (crit = +255.0°C) after: acpitz-virtual-0 Adapter: Virtual device temp1: +0.0°C (crit = +255.0°C) I've had a Linux Mint 17 before Ubuntu 15.10. No issues were in Mint. Before Mint, I've used a Kubuntu 14.04, 14.10, no issues either. I've tried to compile old versions of linux kernel (from the official git repo) and I noticed, that 3.16 kernel was the latest, where fan works properly. 3.17-rc1 breaks it. According to git commit history, 3.17 kernel have many commits related to ACPI/PM fixes. My guess is that kernel doesn't restore thermal sensor device from sleep properly since 3.17.
