Title:
  Repeated freezes when running on battery power

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  My Macbook Pro 3,1 started freezing on battery power just after I
  upgraded from linux-image-3.2.0-10-generic 3.2.0-10.18 to linux-
  image-3.2.0-12-generic 3.2.0-12.20. It was rock-solid on both AC power
  and battery power before upgrading to 3.2.0-12. It remains fine on AC
  power.

  I believe the battery in the system to be healthy - it is relatively
  new and holds a 3hr charge. The other hardware seems fine too, and
  given that the freezes started after a kernel upgrade I suspect a
  software (power management?) problem rather than a hardware problem.

  To reproduce:
  1) Unplug from AC power
  2) Wait 2-30mins

  Symptoms of the freeze include:
  * Mouse is frozen
  * Internal keyboard is unresponsive; can't switch to a VT either
  * USB devices plugged in after the freeze do not get powered on
  * Network connections dropped; the machine doesn't respond to ping after the freeze

  I haven't seen anything in syslog that I can attribute to the freezes.
