The machine is 64-bit capable (Core2 Duo), but the kernels I'm running for this are 32-bit, so I doubt that the 64-bitability is relevant. I'd love to see what happens with a 64-bit kernel, but I never get back from suspend with it (and that's not a recent regression). Carlos is also seeing this with a 32-bit kernel (on P4 Xeon with HT).
Please don't take my git bisection result too seriously: that's where it led when I fudged things around enough, and treated blank screens as manifestations of the problem, which very likely they're not (there's some other bug which makes it very variable how quickly I resume). And also, I wasn't checking how many cpus came up each time: I wouldn't be surprised if at some points in your series only one would come up, which would then look like a "good" point to me.
Thanks, Hugh
