Title: Suspend fails in Ubuntu and Kubuntu 18.04 but works fine in Ubuntu and Kubuntu 17.10 (and on Kubuntu 18.04 using kernel 4.14.47) Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: Fix Released Status in linux source package in Cosmic: Fix Released Bug description: ===SRU Justification=== [Impact] Systems with acpi-lpss can't do S3/S4 on Bionic. [Test] Users confirmed these patches work for them. [Fix] Commit a192aa923b66a (ACPI / LPSS: Consolidate runtime PM and system sleep handling) applies quirks for both runtime and system suspend. This causes problems for some systems, so avoid using quirks on S3 and S4. [Regression Potential] Low. These patches are in upstream stable, and it brings back driver's old behavior. ===Original Bug Report=== I have installed Kubuntu 18.04 on 3 different machines (my friend's and my own) with no suspend problems but my HP Pavilion 11 x360 does not suspend. It suspends fine with Ubuntu 17.10, Kubuntu 17.10, Devuan Jesse, Devuan ASCII and Windows 10 but fails with Ubuntu 18.04 and Kubuntu 18.04. I have also tried suspend using a live USB of 18.04 on this machine and it fails in the same way, so does not appear to be caused by any additional programs that I had installed. By installing an older kernel (4.14) on Kubuntu 18.04 the suspend function works as expected. Running Kubuntu 18.04 with kernels 4.15, 4.16, 4.17 results in the suspend failure that freezes the machine and requires a hard reset. Correct behaviour is - Screen goes blank, fan goes off, power LED flashes to show machine is in suspend. Pressing power button triggers 'resume' function. What happens - Screen goes blank, fan stays on, power LED stays on. Machine stays in this state and does not respond to any keyboard interaction, mouse movement or power button presses. Ctrl + Alt + f1 (or f2, f3, f4 etc) does not get any response. The only way to use the machine is to shut down by holding down the power button. Checking the logs suggests that the machine believes it is in suspend mode sleep [deep] when it isn't. Having to hard reset to get any response means that the kernel logs say no more than sleep [deep] pm-suspend also results in the same problems with kernels 4.15 and 4.16, but works fine with 4.14. It is curious that a machine that suspends fine on an earlier 4.14 kernel no longer works with 4.15 and above, whilst 3 other machines (including one with pretty similar hardware) do not exhibit this problem. There are only a handful of questions about it on the forums but at least 3 other people have the same problem: https://askubuntu.com/questions/1029405/ubuntu-18-04-crashes-on- resuming-from-suspend https://askubuntu.com/questions/1041369/after-upgrading- from-17-10-ubuntu-18-04-wont-sleep-suspend I am attempting to round up anyone else with the same issue and point them to this bug report.
