[Bug 993472] New: Resuming hibernated system leads to complet reboot
http://bugzilla.opensuse.org/show_bug.cgi?id=993472 Bug ID: 993472 Summary: Resuming hibernated system leads to complet reboot Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: cookie170@web.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Current TW on Lenovo T450s, legacy boot, no UEFI. /home is encrypted (LUKS). RAM 8BG, Swap 4 GB in /dev/sda1. Kernel-parameter: resume=/dev/sda1 splash=verbose quiet showopts plymouth.enable=0 . Resume from hibernated system leads to reboot, I'll elaborate: I send the system into hibernate via KDE-button. Screens wents black, flickers, mouse reappears, it takes some time (around a minute) and then the computers is off. No problem so far. I close the lid. I open the lid, computer boots, behaves as if resuming. When resuming worked, there was a little flicker just before the graphical screen asking for my password appeared. But now, the computer reaches this point, but then just reboots. This was an issue since monthes, hibernate was not stable. But now, since a week, it doesn't work at all. s2ram is stable. I've seen this bug: https://bugzilla.opensuse.org/show_bug.cgi?id=842285 . However, we are on a current TW with dracut. I'd be happy to provide more information, but please consider I'm a user, not an expert. Thank you! -- You are receiving this mail because: You are on the CC list for the bug.

From my point of view it is not necessary to backport the improvements from 4.8 to 4.7, I can live with the 4.4 kernel for the time being.

Did you see it with 4.7.x kernel? A nasty S4 bug should have been fixed there.

Well, there is another fix included in 4.4.x SLE12-SP2 / openSUSE-42.2 kernels that isn't in 4.8 upstream yet: the workaround for i915 hibernate resume. Maybe this hits on yours, too.
The notebook I'm using comens with an intel chip, no other GPU, so yes, it uses i915. OK, so I'll stick to the leap kernel.
In anyway, I backported the patches I've added to stable and master branches. Please check kernel-of-the-day once after they are pulled.
This here: http://download.opensuse.org/repositories/Kernel:/HEAD/standard ? Because it is a week old... Of course, I'll test happily. -- You are receiving this mail because: You are on the CC list for the bug.

Rather this one for TW kernel: http://download.opensuse.org/repositories/Kernel:/stable/standard/ -- You are receiving this mail because: You are on the CC list for the bug.

Seems better, resuming worked for a couple of times; if I experienced unexpected reboots, I'd give a word on this list. Kernel: 4.7.2-2.g8a962cf-default, but the Leap kernel worked also and booted much faster. However, thank you! -- You are receiving this mail because: You are on the CC list for the bug.
