I've got another, fully reproducible but nevertheless neglected ACPI problem, already mentioned in #13894: https://bugs.freedesktop.org/show_bug.cgi?id=22126. Well, it's probably far-fetched, but maybe the two are somehow related... Can't you perhaps suggest a way forward there? Or some tricks to create a reproducible test case here? Btw. my gut feeling is that hibernation is getting slower with each kernel release. I didn't measure it, and didn't even care about comparable initial states... But could anything explain this, or is it sheer impatience? -- Regards, Feri. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
