+ This happens identically with both Thinkpad T410  and T510 models (intel
  integrated graphics, nvidia discrete graphics).  The first
  suspend/resume completes successfully.  The second suspend appears to

  continues to pulse).  Pressing the power button again causes a reboot
  (no other buttons seem to do anything in this state).

  That's the DRAM Controller.
  
  Same results from the "xterm" session, and also without X, so no gnome-
  power-manager interactions.
