Title:
  Laptop suspend fails occasionally

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: acpid

  I have a Thinkpad T60 laptop, and using xfce-power-manager have
  configured the laptop to suspend always when the lid is closed.
  However, after upgrading to XUbuntu 10.10, the laptop occasionally
  (maybe once a week) freezes when attempting to suspend.  The laptop
  often gets very hot, and when opening the lid it finally suspends.  A
  year or two ago I had a problem that the laptop randomly unsuspended
  without opening the lid, but at least in Ubuntu 10.04 I never had any
  problems.

  The suspend stops at the following position (from dmesg):

  [162033.690414] PM: Syncing filesystems ... done.
  [162034.083129] PM: Preparing system for mem sleep
  [187754.893240] Freezing user space processes ... (elapsed 0.01 seconds) done.
  [187754.908100] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.

  And the same in /var/log/messages:

  Attached is a full dmesg dump from a close lid - failed suspend -
  opening lid - suspend - resume.  (The laptop was accidentally on the
  whole night.)

  The first time I noticed this was after I had configured my 3G mobile
  network over Bluetooth, so it *might* be related to that.  However
  there are cases where after using 3G I've suspended and resumed
  successfully, and only later the suspend fails.
