Update: I noticed that after the system hangs (e.g. plugging in a HDMI device while on battery), upon subsequent restarts the system fails to resume on battery, no matter what kernel I load.
Once I fully shutdown and cold start, resume starts to work. As if it has to do with some internal state loaded on warm boot? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638131 Title: Resume fails while on battery To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1638131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
