http://bugzilla.opensuse.org/show_bug.cgi?id=951548 Bug ID: 951548 Summary: system takes over a minute to fully wakeup after suspend, hibernate is even faster Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 RC1 1 Hardware: x86-64 OS: openSUSE 42.1 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: abittner@opensuse.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have that other bug #boo950657 where I was reporting something slightly related On my testing system (amd apu, 32gig ram, single sata hdd, vga screen), after systemctl suspend. When it powered down, the atx power led pulsates indicating that it is sleeping in some way. And then a few seconds later I wake the machine again e.g. via keyboard keypress, it immediately semi-wakes (cpu fan rotating slower, but hdd waking again spinning up) it stays in this calmer state for over a minute, no hdd activity other than spin is being heard and no hdd led activity seen. The screen stays in powerdown mode as well all this time. After the minute+ screen wakes up the hdd does some activity audibly heard and then the login/lockscreen is being presented. I kind of figured, that hibernate mode is actually quicker for me. When I first discovered this behavior I even reset my machine after maybe like ten or twenty seconds as I had thought that suspend or sleep mode was not working at all and freezing my machine and having incompatibilities. What does the linux kernel or these power states do during this minute? Am I misunderstanding the suspend and the hibernate states? Hibernate does write the ram content to disk, doesnt it? And then powers off. As after hibernate my system goes through POST/Bios and doesnt present the grub menu but immediately boots back into the state where it left off, so reads back the ram contents from disk into memory and continues. But what does suspend actually then do so differently that it takes this long in some limbo state? Is this suspend supposed to be the same state as if I had a laptop and closing the lid? Does the linux kernel have more additional states? Maybe I am only looking for a laptop lid closed state or similar to be able to quickly recover from it. Waiting a minute to wake up is not really usable.
