Can everyone check which version of the Intel microcode updates package is installed? There's a suggestion the bug may be due to that. You should see:
$ apt-cache policy intel-microcode intel-microcode: Installed: 3.20180108.0+really20170707ubuntu16.04.1 Candidate: 3.20180108.0+really20170707ubuntu16.04.1 This is the package that backed out the Intel 20180108 microcode with the previous 20170707 release. Please report back if hibernate still fails with the 20170707 microcode and kernel 4.13.0-25 or later. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743094 Title: [regression] hibernation (freezes on resume) since 4.13.0-25.29 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
