Title:
  Linux 3.2.0-48 Kernel Fails to Suspend

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  When a recent Ubuntu update replaced the 3.2.0-45 Linux kernel with
  3.2.0-48, suspending my IBM ThinkPad T60 laptop started failing.

  I suspend my T60 using a shell program that invokes rtcwake(8) as
  follows:

  rtcwake --mode mem --utc --time $(date -d "$wakeupTime" +%s)

  where $wakeupTime is either "2150 tomorrow" or "2150 today", depending
  upon whether the program is invoked before 9:50 pm or not.  In either
  case, suspend succeeds using the 3.2.0-45 kernel by flashing the
  laptop "moon" LED while suspend is in progress, becoming a solid LED
  when suspend completes. With the 3.2.0-48 kernel, the LED begins
  flashing but never turns solid. The T60 can only be restarted by
  powering it off and back on.

  This failure is independent of whether the video is in graphics mode
  (Xorg server) or text mode (virtual console).
