Since Ubuntu 15.10, we have a regression: Suspend to RAM never works, the workaround with first suspending to disk no longer works. I have tested this with both the current Ubuntu kernel (4.2.0-22-generic #27-Ubuntu SMP Thu Dec 17 22:57:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux) and the latest kernel from http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.4-rc5-wily/ (4.4.0-040400rc5.201512140221).
With Arch Linux on the same machine, suspend to RAM works after hibernate, so this looks like a regression introduced with Ubuntu Wily. What has changed with suspend-resume from 15.04 to 15.10? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1375995 Title: [HP Compaq dc7800 Small Form Factor PC] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1375995/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
