But that bisection may be leading toward a dead end or at least a moot point. The behavior which I am calling "bad" there is different from what I am currently seeing in later RCs and in 4.14.0.
In, for example, my last "bad" commit 126f760ca94, upon suspend the machine does actually suspend but can't wake. In 4.14rc6, 4.14rc8, and 4.14, now upon suspend I am seeing the display power off and everything spins down but only for a moment -- then it immediately resumes. wifi and graphics seem to work OK at that point. The main remaining problem is just failure to remain suspended. That is true at least upon first suspend. In one of those builds I did see a case where a second suspend would spin down, try to spin up, but although the display backlight did come back on the machine remained unresponsive. I am not sure why the later RCs and in particular rc6 switched to this new failure mode. In my earlier notes it's clear that they used to be failing more like the way 126f760ca94 still behaves. -- 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/1726061 Title: Inspiron 5565 suspend issues after 17.10 upgrade Status in linux package in Ubuntu: Confirmed Bug description: On my Inspiron 5565, 17.10 seems to work fairly well, unless I try to suspend. Suspend shuts off the display but doesn't seem to actually shut off the CPU -- fans still run. When I move the mouse the display comes back on but upon entering my password sometimes the session crashes and I am dumped back to the login screen; sometimes the session is still there but wifi is either disabled (all wifi-related menu items gone) or visible (with question mark) but non-functional. In any case once I have suspended I cannot shut down or reboot any way other than the hard way, by holding the power button for several seconds. Doesn't seem to matter whether I am using X or Wayland. Suspend works mostly fine if I choose the 4.10 kernel from GRUB... although I am prompted for login more times than necessary on resume.
