I installed the 4.6rc kernel and did some quick checks. I could not reproduce the issue. However the ZFS module is missing which might be a part of the problem. I'm using lxd containers with ZFS enabled and noticed that the crashes seem to happen more likely when containers are started.
Aside from pulling the upstream zfs sources and building them myself are there other ways to get the module for the RC kernels? -- 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/1580943 Title: Kernel is very unstable on Dell XPS15 (model 2014) Status in linux package in Ubuntu: Incomplete Bug description: The system is halted on my machine in different scenarios: 1) Running debootstrap, the oops happens when chroot tries to mount a kernel filesystem from the host 2) Running ubuntu-emulator create from the Ubuntu SDK IDE: http://pastebin.ubuntu.com/16373613/ 3) USB devices are disconnected sometimes, they are immediately reconnected but when a ubuntu phone is attached chances are high the system might hang as well I will attach more logs as soon as I hit the problem again ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-22-generic 4.4.0-22.39 ProcVersionSignature: Ubuntu 4.4.0-22.39-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 NonfreeKernelModules: zfs zunicode zcommon znvpair zavl ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC3: zbenjamin 3703 F.... pulseaudio /dev/snd/controlC2: zbenjamin 3703 F.... pulseaudio /dev/snd/controlC1: zbenjamin 3703 F.... pulseaudio /dev/snd/controlC0: zbenjamin 3703 F.... pulseaudio CurrentDesktop: Unity Date: Thu May 12 11:36:15 2016 HibernationDevice: RESUME=UUID=ffa1bf0f-220e-4288-9b84-9970818474fc InstallationDate: Installed on 2016-03-15 (57 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Alpha amd64 (20160307) MachineType: Dell Inc.
