Title:
Hardware-specific: Fan is running at full speed on resume
Status in linux package in Ubuntu:
Confirmed
Bug description:
This bug is related to Asus 1025C laptop.
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.
