I traced it down to the DRM driver: without X and DRM unloaded, I had more than 200 suspens in a row without any failure. With 2.6.29-rc6-00029-gf7e603a, even with DRM unloaded the computer hangs at suspend time after some attempts. I also tried other 2.6.29-rc kernels, and all had unstable suspend behaviour. I can't give any further details, as the console is dark and I have no serial console. Any hints what I might try except for bisecting? Regards, Tino
