[Bug 532374] [NEW] [Lenovo 2537AD3, 2537AB8] one successful suspend/resume per boot

[Jeremy Zimmer]

Public bug reported:

This happens identically with both Thinkpad T410 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.
