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
  (although it seems to be related to how it interacts with the kernel,
  thus maybe the problem is kernel-related).

  WORKAROUND: Boot from GRUB with the nomodeset parameter. The graphics
  performance becomes terribly slow.
