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.
Cheers

perf/urgent
6c0aca288e726405b01dacb12cac556454d34b2a
("x86: Ignore trap bits on single step exceptions")
And should reach mainline soon.

This bug is still present in 2.6.37-rc2, but (as the original reporter)
I now doubt it should be classified as a regression. It looked as if
it was a regression because in the 2.6.35 kernel (the first kernel to
include intel idle), intel idle was available as a kernel module and
that module never in fact loaded on my hardware and so never caused a
hang. In 2.6.36 onwards, intel idle is only available directly compiled
into the kernel and that is when the hang became apparent: subsequent
testing shows that the hang also occurs with 2.6.35 if intel idle is
compiled in rather than as a module.
So it is a bug, which is still present, but not necessarily a
regression.

Can you bisect? Does this patch help?

OK, dropped from the list of recent regressions.

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

[drm:atom_execute_table_locked] *ERROR* atombios stuck executing E576 (len 105,

So I did this (local hack only, obviously NOT for mainline) to work around that

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.
