I don't know whether it is relevant, but I ran an apt-get update / apt- get upgrade today and since then I cannot boot anymore at all on the newer kernels. I always see the messages now that you see on the images. The only kernel I was able to boot, is "4.2.0-19-generic #23-Ubuntu SMP Wed Nov 11 11:39:30 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux". I guess it has something to do with Ubuntu updates that is not aware of the newer kernels, but still I thought, I better mention it.
Those were the packages that I updated today: 2015-12-10 09:28:18 install libaudio2:amd64 1.9.4-3 1.9.4-3 2015-12-10 09:28:18 install libgsoap7:amd64 <none> 2.8.22-1 2015-12-10 09:28:18 install libmysqlclient18:amd64 5.6.27-0ubuntu1 5.6.27-0ubuntu1 2015-12-10 09:28:19 install dkms:all <none> 2.2.0.3-2ubuntu6.1 2015-12-10 09:28:19 install libqt4-network:amd64 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:19 install libqt4-script:amd64 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:20 install libqt4-sql:amd64 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:20 install libqt4-xmlpatterns:amd64 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:20 install libqtgui4:amd64 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:21 install libqt4-declarative:amd64 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:22 install libqt4-opengl:amd64 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:22 install libqt4-sql-mysql:amd64 <none> 4:4.8.6+git64-g5dc8b2b+dfsg-3~ubuntu8 2015-12-10 09:28:22 install libvncserver1:amd64 <none> 0.9.10+dfsg-3 2015-12-10 09:28:22 install virtualbox-dkms:all <none> 5.0.10-dfsg-2ubuntu1 2015-12-10 09:28:23 install virtualbox:amd64 <none> 5.0.10-dfsg-2ubuntu1 2015-12-10 09:28:25 install virtualbox-qt:amd64 <none> 5.0.10-dfsg-2ubuntu1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1516215 Title: kernel 4.x has issues with lite-on sata controller in dell xps 13 (2015) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1516215/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
