I think I have the same problem on an Acer Aspire 5920 laptop. The machine hangs very early in the boot process on Ubuntu 3.19.0-17-generic, but boots successfully using recovery mode, or booting 3.19.0-16-generic. Let me know if I can provide further info. I may need detailed instructions. Thanks.

I'm not sure it matters or what info ubuntu-bug collects, but I didn't do "ubuntu-bug linux" since it gave an error: "Problem in linux-image-3.19.0-13-generic The problem cannot be reported: This is not an official Ubuntu package. Please remove any third party package and try again." I did ubuntu-bug Xorg just to get some collection of info, NOT saying xorg is the fault. Note that this bug report is NOT about that kernel but the most current (and maybe one or two others). Yesterday I wasn't having this problem with kernels (at least not the newest one I had not installed.. I may have had different problems, do not believe hardware broken though). $ ls -lrt /boot/initrd.img-3.1* -rw-r--r-- 1 root root 19976179 apr 10 17:20 /boot/initrd.img-3.13.0-47-generic -rw-r--r-- 1 root root 21779681 apr 11 14:54 /boot/initrd.img-3.19.0-13-generic -rw-r--r-- 1 root root 21782845 apr 19 13:54 /boot/initrd.img-3.19.0-15-generic -rw-r--r-- 1 root root 21733320 maí 8 20:26 /boot/initrd.img-3.19.0-15-lowlatency -rw-r--r-- 1 root root 21780289 maí 8 21:04 /boot/initrd.img-3.19.0-17-generic I believe I've been running 3.19.0-15-generic for the last few days. I just run the most recent one (usually - but not now because of the problems below). Today (this evening) I upgraded some stuff including the kernel. 3.19.0-17 does not boot up. I've tried several times and get a blank screen. I may have gotten something else, a splash-screen (not as far as login-screen), on the first try. DO not count on that as I may misremember. Then booting into 3.19.0-15-generic I could log in, so it seems the kernel above is the problem. Note I also upgraded more, say networking. AND now while I can log in, that kernel quickly froze (twice just after starting Chrome w/lots of tabs) - in a way I've never seen - the CAPS LOCK and the light to the RIGHT (NOT NUM LOCK to the left) where blinking in sync. I may have forgotten (or not?) to try a virtual terminal as this seemed a sure indication that something was wrong. [I also booted into just-installed 3.19.0-15-lowlatency and got the blinking lights.] Then I booted into 3.19.0-13 and am now for a much longer time in Chrome, so far no freeze.. [I was doing apt-get autoclean today, deleting kernels, so maybe I'm wrong about the exact version of the kernel I was running without problems, but at least all the info on kernels that do not work are right.] ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: xorg 1:7.7+7ubuntu4 ProcVersionSignature: Ubuntu 3.19.0-13.13-generic 3.19.3 Uname: Linux 3.19.0-13-generic x86_64 NonfreeKernelModules: wl .tmp.unity.support.test.0: ApportVersion: 2.17.2-0ubuntu1 Architecture: amd64 CompositorRunning: None CurrentDesktop: Unity Date: Fri May 8 21:50:41 2015 DistUpgraded: 2015-04-06 16:46:01,057 DEBUG enabling apt cron job DistroCodename: vivid DistroVariant: ubuntu ExtraDebuggingInterest: Yes GpuHangFrequency: Continuously GpuHangReproducibility: Yes, I can easily reproduce it GpuHangStarted: Today GraphicsCard: InstallationDate: Installed on 2014-08-21 (260 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) MachineType: Dell Inc.
