[Bug 1565864] Re: Hardware-specific: Fan is running at full speed on resume

 

raxp, as per
https://www.asus.com/Notebooks/Eee_PC_1025C/HelpDesk_Download/ an update
to your computer's buggy, insecure, and outdated BIOS is available
(1301). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

Title:
  Hardware-specific: Fan is running at full speed on resume

Status in linux package in Ubuntu:
  Incomplete

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.
