1. before suspend, examine and remember all values of /sys/devices/virtual/thermal/cooling_device*/cur_state
2. after suspend, restore all values mentioned above.

OR, for simplicity, just set the values of
/sys/devices/virtual/thermal/cooling_device*/cur_state periodically.

Title:
  Laptop Fan always on after resume from suspend to RAM

Bug description:
  Binary package hint: initramfs-tools

  After doing a suspend to RAM, the fan is always "on" on my laptop, even if temperatures are low (where the fan would normally be off before going to sleep mode for the first time).
  I removed the /usr/share/initramfs-tools/hooks/thermal script and now everything works fine (fan behaviour is not anymore affected by the suspend to RAM). It seems like this script does a wrong initialization of something which is not needed on my PC.
  My laptop is a Toshiba satellite A100-308 with dual core centrino. I have a basic standard ACPI support, toshiba_acpi and omnibook kernel modules do not work with my hardware.
