It is regular suspend to ram. I feel now confident in saying that with the debug patch resume from STR is 100% reliable. And the two workarounds I was using to improve resume reliability are no longer needed: - unloading e1000e before suspend - using aggressive powersave setting on snd_hda_intel to ensure that sound controller was already sleeping before entering suspend I don't think we have any theory yet on how those workarounds were helping to improve things, right? > Well, how stable has hibernate been on that particular machine > historically? I cannot comment on this as I have not owned this laptop long enough. One other thing: the ohci1394 "irq 19: nobody cared" issue is definitely unrelated as I just got one during a resume with the debug patch.
