I've ran SuperTuxKart for 9 hours (620/50000 laps) in total, without suspend
the machine.

The result: SuperTuxKart didn't crash or hang at all. I also ran glxgears in
the middle of it and no hangs or crashes. Stability is really good without
suspend.

I see lots of these messages on my dmesg however:
