Title:
  Problems with "hibernate"

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  OS: Ubuntu 12.04 x86_64, Hardware: Lenovo T410s (using Intel
  graphics), i5-540 M.

  When running pm-hibernate, and when according to "free" the RAM
  occupation is below the swap size, hibernation does not take place.
  When running subsequently "cpufreq-info", only one thread shows up
  (there should be 4). To put the CPU into its "normal" state requires a
  reboot.

  A partial fix: executing (as root):
  sync; echo 3 > /proc/sys/vm/drop_caches
  sync; echo 0 > /proc/sys/vm/drop_caches
  cat /proc/sys/vm/drop_caches
  frees memory. A subsequent hibernation (with "pm-hibernate") then works.

  Thank you,
  François P. Rotzinger
