That doesn't seem to be related to grub.

Title:
  Ubuntu 16.04 LTS stalls during boot

Status in Ubuntu:
  New

Bug description:
  Hardware: Mac Pro 5,1 (mid-2013)
  Platform: Ubuntu 16.04 LTS Server
  Details of Issue: 

  Though Ubuntu 16.04 LTS Server successfully installs, upon boot it
  stalls on trying to utilize the radeon driver. Specifically the boot
  process stalls with the following message displayed:

  fb: switching to radeondrmfb from EFI VGA

  This is ignored when one boots ubuntu into recovery mode then selects
  resume from the menu as it skips some normal checks before continuing
  the boot process. Additionally, if one modified the grub boot options
  and sets to boot the kernel with "nomodeset" and then blacklist the
  driver, the entire issue is avoided and the machine boots as normal.
