If you are referring to the '"resume-trace" debugging procedure for finding buggy drivers', I'm still evaluating if this is beyond my skills.
In particular I don't understand this paragraph: "Caveat Emptor: Using the following debug suggestions will radically change the values in your RTC chip, so much so that your file system will think it has been eons since the last fsck. You can avoid a long fsck delay by using 'tune2fs'. For example, 'tune2fs -i 0 /dev/sda1' disables fsck on boot. But first you'll want to use 'tune2fs -l <partition>' to find your current settings - look at the "Check interval" setting." Do I need to disable something in boot before or after the resume- tracing proceduce? What is the consequence of file system thinking it has been eons since the last fsck? Sicne I don't wish to mess my computer, it would be great if someone could provide fool proof instructions for this part, including suggested terminal commands in the right order. -- 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/1618550 Title: [HP 15-r085no Notebook PC (ENERGY STAR)] Suspend/resume freezes Status in linux package in Ubuntu: Incomplete Bug description: My HP notebook won't wake from suspend with 16.04 LTS, waited for the latest 4.4.0-36 kernel update before reporting this bug. Computer goes to suspend, but attempts to wake it up just start the fan (and HDD) while the display remains black. Also tested this with the mainline upstream kernel 4.8.0-040800rc3-generic. With this version there was different behaviour but still a bug: the display woke up but Ubuntu was very unstable, did not connect to Wifi and the GUI froze very soon after resume.
