Title:
  HP Pvilion dv6 overheats and block

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: grub2

  The normal install doesn't recognize correctly acpi and fan are not
  managed. The system goes hot and dies.

  Symptom:
  the directory /proc/acpi/thermal_zone/ is empty

  Correction:
  in /etc/default/grub change the line

  GRUB_CMDLINE_LINUX_DEFAULT='quiet splash'

  in

  GRUB_CMDLINE_LINUX_DEFAULT='quiet splash acpi_osi="Linux"'

  execute sudo update-grub and reboot

  Now the directory should be populated
  tree /proc/acpi/thermal_zone/
  /proc/acpi/thermal_zone/
  └── TZ01
      ├── cooling_mode
      ├── polling_frequency
