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

[Tom Gelinas]

Lanoxx, please look 1 post above yours, which refers to the bug report
for x61s. https://bugs.launchpad.net/oem-priority/+bug/569882 . Nobody
without an i5/i7 Thinkpad is affected by this particular bug.

** 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).
+ This happens only to Thinkpads with i5 or i7 processors, both Thinkpad
+ T410  and T510 models are affected (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.

- Thinkpads X201, T410, T510, W510 
+ Thinkpads X201, T410, T510, W510
  & possibly T410s
