	Hello Ben,

  I've done the manual bisecting with 2.6.32.28 patches, and with 6
tries (and 2 more checks to be sure), I found that the patch causing
hibernation resume failures was :

x86-hotplug-use-mwait-to-offline-a-processor-fix-the-legacy-case.patch

I've done about ten successfull hibernation/resume cycles with a
2.6.32-30 without this patch, and I'm using it since the end of my
bisecting with success.

I've also read on bug #611750's log that  the new
linux-image-2.6.32-5-686_2.6.32-31_i386 could have a fix for this
problem, perhaps you could look if there is a patch in this latest
version fixing the previous faulty patch I've identified here.

  With regards,
	Fred.
