As I just got the computer, I did not try any other kernel/distro so far. I'm trying out the v4.8 kernel now, and this issue seems to be fixed -- thanks for the hint! I will test it over the day some more, and mark it 'kernel-fixed-upstream' if all is fine.
There is some other weird behavior with this kernel though: the computer makes audible noises when under load, something like a very high pitched whisper (so no fan) that I have never had with the default 16.04 kernel. -- 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/1618075 Title: freeze on wake from suspend on 16.04, Dell Latitude e7470 Status in linux package in Ubuntu: Incomplete Bug description: On waking up from suspend, the display stays black. I cannot switch to the console, nor kill the x server. After a while the laptop reboots itself, or alternatively, I power it off. It does not happen on every suspend, but very often. I happens most of the times when the laptop was recently connected to the Dell dock, which connects to an external display via DVI and ethernet. My system is Ubuntu 16.04 with all updates, kernel Ubuntu 4.4.0-34.53-generic 4.4.15 on a Dell Latitude E7470. FDE is enabled, swap is on the encrypted partition. I've tried a 4.6 kernel from mainline-builds, that did not solve the problem. I'd be very grateful for any advise on what to do about this.
