Title:
  sometimes suspend fails and the whole system freeze with high CPU
  usage

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  About one time out of 10,
  when I close the lid of my laptop (MacBook 2,1),
  the system does not suspend.

  Apparently the CPU is running high,
  because when I return to my laptop,
  it is very hot and the fan is turning full speed.

  When I reopen the lid the system does not resume.
  Mouse and keyboard are not active.
  The only way out is to switch off the laptop.
