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
