Hello Ben, I've run the 2.6.32-31 Debian kernel without the identified faulty patch (x86-hotplug-use-mwait-to-offline-a-processor-fix-the-legacy-case.patch) since about two weeks, using multiple hibernation cycles, without any problem.

One more datapoint : I also upgraded to 2.6.32.31 as packaged in testing, without further problems on my 1005PE. I have used it since its apparition in testing (that's 8 days and 8 hours according to uptime), using my machine as usual (meaning 2-5 hibernations per day) without shutdown or reboot. Other models may be pickier ?

Hello Ben, I've actually found the culprit's commit. I has been harder than I thought, as at first git bisect process, I was always finding 'good' systems, ending with latest commit of 2.6.30 (which is unrelated, about powerpc) :-( I doubted of my rebuild system (I wasn't do a 'make clean' between kernel recompilations, I'm not sure if it's mandatory) and finally found that the bug (resumimg from hibernation fails), I had to wait some time, and remove the current plug for some time, or at least do a cold boot.
