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.
