Yuri Ribeiro Sucupira, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following: 1) The one to test is at the very top line at the top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .
If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: xorg (Ubuntu) Importance: Low => Medium -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1608042 Title: 64-bit XUbuntu 16.04 "Xenial" hybrid graphics (Intel + AMD): AMDGPU crashes / freezes / hangs entire system Status in xorg package in Ubuntu: Incomplete Bug description: COMPUTER: Dell Inspiron 5548 laptop CPU: Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz GRAPHICS: Intel-AMD hybrid: - CPU-integrated: Intel Corporation Broadwell-U Integrated Graphics (driver: i915) - GPU: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265] (driver: amdgpu) OPERATING SYSTEM: 64-bit GNU/Linux XUbuntu 16.04 "Xenial" KERNEL: 4.4.0-31-generic PROBLEM: system hangs / freezes very frequently. I have Xscreensaver installed and noticed that when it's running an OpenGL animation (screensaver) and I move the touchpad pointer the screen freezes. I can still turn the keyboard LED backlight on and off (hence: keyboard doesn't stop working) but the pointer won't move (touchpad is locked) and I can't Ctrl-Alt-F[1-6] (switch TTY/terminals). Only solution is to power off my laptop (press and hold the power button). I usually select the "Molecule" screensaver (it uses OpenGL), then I click the "preview" button and wait for about 20 seconds, then I click the touchpad and the computer hangs. When I used XUbuntu 14.04 "Trusty" with AMD's fglrx (proprietary) driver I didn't experience such issue. After upgrading to 16.04 "Xenial" (which doesn't support fglrx module/driver) amdgpu module is loaded by default but very frequently hangs the entire system. Sometimes I'm quick enough to go to TTYS1 and then I get to see some messages such as "HARD LOCKUP on CPU0" and "HARD LOCKUP on CPU1". However, it's not a hardware problem because I've already executed the Dell Hardware Diagnostics straight from the boot (it's an EFI utility), it tested all the hardware components (CPU, GPU, RAM, keyboard, touchpad, hard disk etc.) and didn't detect any faulty component. The attached file "amdgpu-bug.txt" is the reason why I'm pretty convinced that the problem is being caused by the amdgpu driver. WORKAROUND: Boot from GRUB with the nomodeset parameter. The graphics performance becomes terribly slow. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 BootLog: CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: XFCE DistUpgraded: Fresh install DistroCodename: xenial DistroRelease: Ubuntu 16.04 DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation Broadwell-U Integrated Graphics [8086:1616] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Dell Broadwell-U Integrated Graphics [1028:0643] Subsystem: Dell Topaz XT [Radeon R7 M260/M265] [1028:0643] InstallationDate: Installed on 2016-07-29 (1 days ago) InstallationMedia: Xubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) MachineType: Dell Inc.
