That one is interesting to me.. I suspect it may be the same cause as for https://bugzilla.kernel.org/show_bug.cgi?id=21952
I have one of those Samsung (N210) Netbooks here: works fine with 2.6.34 and earlier, but fails to come out of suspend on 2.6.35/2.6.36 (haven't tried 2.6.37).
So perhaps add 21952 to the list, or link it to the 21652 (kind of amusing how similar the bug numbers are..).
My non-Intel graphics notebook (has ATI X1400 graphics) also has a resume regression with 2.6.36. But it does work fine with 2.6.35 (and earlier, back many years). As a result, I'm stuck with 2.6.35 for the time being, and lack the time for a concerted debug effort on 2.6.36+ right now.

It now comes back at resume time.
But suffers long delays (also sometimes with 2.6.35) doing this:

My non-Intel graphics notebook (has ATI X1400 graphics) also has a resume regression with 2.6.36. But it does work fine with 2.6.35 (and earlier, back many years). As a result, I'm stuck with 2.6.35 for the time being, and lack the time for a concerted debug effort on 2.6.36+ right now.
Can you bisect? Does this patch help?

It's be nice if you could bisect to track down when those started.

I think so. It didn't used to resume from suspend with 2.6.36, and now it does.

It'd be even nicer if they hadn't started. :)
What kernel release first had that atom/ops table in it? I'll try that.

2.6.31 or 32 was when radeon kms got merged IIRC.
