Did a suspend resume test, with 15.10, kernel v4.3. No external monitors connected.
Executed: sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" several seconds after suspend (system is really suspended, blue suspend light is glowing), put it in resume with power button. As before, other lights go on very shortly, system crashes (all lights off, sound of hdd shutting down not normally, same as long-pressing power button while system running), few seconds after that, system boots by itself, so not resumed. Did same test with an extra udev rule so that resume with external mouse or keyboard works, same behaviour. Added dmesg_crash.txt and cat /proc/acpi/wakeup output ** Attachment added: "dmesg_crash.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1255700/+attachment/4520974/+files/dmesg_crash.txt -- 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/1255700 Title: [HP EliteBook 8740w] suspend/resume failure Status in linux package in Ubuntu: Incomplete Bug description: Put system in suspend. Quickly wake it up via sleep button on the keyboard. (within about 3 to 5 seconds) System goes on briefly (about 3 to 5 seconds), crashes and reboots. This crash happened with the lid closed all the time and a separate keyboard connected. This issue also happens with the lid open, but mostly I don't have a separate keyboard connected. In that case it will only wake up by pushing the power button. Lid opening doesn't trigger a wake, but I guess I will have to file a separate bug report for that. WORKAROUND: If I wait much longer (say a minute or longer) before waking the system, resume works perfectly. WORKAROUND: Press power button instead of suspend button.
