Public bug reported: On Kubuntu 15.10 I had a problem with the suspend functionality on my laptop. The second time it suspends it would hang, and a hard reset was necessary to resolve the problem. After the update to 16.04, the problem was resolved (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1552216)
I updated my laptop using the xenial-updates repository. After the upgrade to linux 4.4.0-31, the suspend issue returned. I have also tried later updates (4.4.0-34 and 4.4.0-36), but the issue is also present in those versions. I therefore still use 4.4.0-28. I tried bisecting, but after a few iterations it messed up my boot partition, and after repairing that, I no longer took the time to finish the bisection. I think bisecting was somewhere in the 29 series of the kernel (see https://launchpad.net/ubuntu/+source/linux/4.4.0-31.50 for changelog) ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-28-generic 4.4.0-28.47 ProcVersionSignature: Ubuntu 4.4.0-28.47-generic 4.4.13 Uname: Linux 4.4.0-28-generic x86_64 NonfreeKernelModules: zfs zunicode zcommon znvpair zavl ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jan 9230 F.... pulseaudio Date: Sun Sep 4 19:42:54 2016 HibernationDevice: RESUME=UUID=321acbbf-9a6a-4825-8f47-a89d56536272 InstallationDate: Installed on 2016-02-03 (214 days ago) InstallationMedia: Kubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 8087:0a2a Intel Corp.
