I'm waiting for it to fail again before posting more info. Once it does I will try the upstream kernel.
But to answer the question, this was happening in 18.04 (kernel version 4.15.0-38-generic) prior to upgrade, and has failed once since upgrade to 18.10 earlier this afternoon. (But as luck would have it, it won't fail on demand for me now!) Last time I can remember this particular system resuming from suspend reliably was probably just prior to install of 18.04 from new - previously it was running 18.04 upgraded from 17.10 (and earlier!) I'll keep an eye on it and report back. Annoyingly, for now though, it seems to be resuming OK! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1800859 Title: Fail to wake from suspend in Ubuntu 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1800859/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
