Yuri Ribeiro Sucupira, thank you for reporting this and helping make
Ubuntu better.

While engaging your WORKAROUND, could you please run the following command once from a terminal by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information:
apport-collect -p xorg 1608042

When reporting xorg related bugs in the future, please do so via the
above method. You can learn more about this functionality at
https://wiki.ubuntu.com/ReportingBugs.

** Description changed:

  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 Alt-F1 (switch 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.
  
- => If I boot from GRUB with the "nomodeset" parameter the problem
- disappears completely, although graphics performance becomes terribly
- slow. But I can then preview the "Molecule" screensaver as many times as
- I want and nothing locks / hangs / freezes.
- 
  The attached file "amdgpu-bug.txt" is the reason why I'm pretty
  convinced that the problem is being caused by the amdgpu driver.
