  Description:  Ubuntu 18.04.1 LTS
  Release:      18.04
  What you expected to happen ?
  Boot successfully.
  What happened instead ?
  After selecting Ubuntu in the grub menu, I am greeted with a black screen 
that flashes text and the computer reboots. This keeps happening until I edit 
the boot parameters and add radeon.dpm=0.
+ I tried to fix the issue by installing a newer version of the kernel and
+ installing the Oibaf's PPA, but the issue persisted.
