Bug description:
System: Mac Pro 5,1 (mid-2012).
I'm unable to boot the Ubuntu 18.04 installer ISO on this system (tried both
18.04.0 and 18.04.3). I was able to boot the 16.04.1 ISO (but NOT 16.04.6) and
installed 16.04 successfully. Then, I upgraded to 18.04. However, when trying
to boot the new kernel (4.15.0-60), it just locks up at the purple screen.
Booting back to 4.4.0-161 works.
