For all 3 (three) PCs (Acer X3-710, B150M Gaming Pro and ASUS P8H67-M PRO):
1. Ubuntu MATE 17.10 & kernel 4.15.x / 4.16.x => Hibernate / Resume from Hibernate works perfectly 2. Ubuntu MATE 17.10 & kernel 4.13.0.21 => Hibernate / Resume from Hibernate works perfectly 3. Ubuntu MATE 17.10 & kernel 4.13.0.y (y >=25) => Hibernate / Resume from Hibernate does not work at all - PC restarts and a few seconds later the monitor goes black and shortly after in suspend mode - keyboard is frozen / dead - pressing any key of the keyboard does nothing, pressing Caps-Lock does nothing - see https://ubuntu-mate.community/t/hibernation-broken-in-kernel-4-13-0-25/15736 4. Ubuntu MATE 18.04 & kernel 4.15.x (x = any available) / 4.16.x (x <= 3) => Hibernate / Resume from Hibernate does not work - PC starts as if I would've rebooted it instead of resuming it from hibernate - I can work normally but previous state / session is not restored - the error window appears stating that "This occurred during a previous hibernation, and prevented the system from resuming properly" - unfortunately it does not offer submit any other bug reports (even if I click "Continue") - it's the same behaviour: for any of the listed PCs when upgraded from 17.10 to 18.04 or fresh install of 18.04 (Beta 1, Beta 2 or Release) This is the reason why I do not thing that kernels 4.15 / 4.16 are the reason for this issue, but I may be totally wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761831 Title: ASUS B150M Gaming hibernate/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761831/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
