[Bug 532374] Re: Lenovo Thinkpads with Core i5 and i7 suspend/resume (with kernel oops) once then fail horribly on next suspend

[Jerone Young]

** Description changed:

  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
  work, but when waking, a few LEDs flicker, but the laptop stays
  suspended (moon LED on the lid stays lit, LED around power button
  continues to pulse).  Pressing the power button again causes a reboot
  (no other buttons seem to do anything in this state).
  
  Per https://wiki.ubuntu.com/DebuggingKernelSuspend:
  
  $ grep -A4 Magic .tmp/dmesg.txt
  [    1.148585]   Magic number: 0:523:347
  [    1.148587]   hash matches /build/buildd/linux-2.6.32/drivers/base/power/main.c:471
  [    1.148615]  pci0000:00: hash matches
  
  That's the DRAM Controller.
  
  Same results from the "xterm" session, and also without X, so no gnome-
  power-manager interactions.
+ 
+ This issue effects:
+ Thinkpads X201, T410, T510, W510 
+ & possibly T410s
