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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1638131 Title: Resume fails while on battery Status in linux package in Ubuntu: Incomplete Bug description: Symptoms -------- Suspend seems to work. Resume only works while not on battery. This used to work before some recent kernel update. However trying some of the older kernels now does not fix the problem: the symptoms are the same.
