[Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
[    0.180576] ACPI: Interpreter enabled


** Description changed:

  Using the -22 or -24 kernel package on an amd64 machine, with or without
  all Ubuntu updates, the hd access light rarely (if ever) turns off. This
  happens with either the stock 250GB 5400 RPM SATA drive or my new 64GB
  Sandforce 1222 SSD. With the stock drive installed, the hd access light
  doesn't seem to correlate with the sound of the disk actually doing
  anything; the light is on even when the disk isn't making any noise at
  all.
