So presumably this will also need to be reverted for 3.0 and 3.2? Or is there something very weird about i915 in 3.4? Ben. -- Ben Hutchings You can't have everything.

Maybe it had even happened in 3.5 once before I got into testing all those 3.4/3.0 images - at my weekend setup there's an external DVI display that won't be fired up by the X200s anyway if the timing isn't right, so that new bug could go by unnoticed there. So it seems the trouble still exists in >=3.5, but it happens way, way less often (my laptop boots once or twice per day). I should get my other system back up running to be able to try and SSH into the laptop next time this happens at home - just in case I could provide any useful output?

Andreas, also make sure your hardware in the bios is configured within the memory types supported by GM45 (DDR2-667/800, DDR3-800/1066, from Intel website listed specifications). I had a similar problem on a G41 machine with same commit, with a pair of DDR3-1333 memory installed it was configured to run at 1333, but the chipset only supports up to 1066, when I forced it back to DDR3-1066 in the bios, the problem vanished.
