[Bug 1753510] [NEW] Cannot boot/install AMD Ryzen 2400G

[Peter Silva]

Public bug reported:

Did a motherboard swap on a trusty old computer that ran ubuntu for 10 years or so. Now it only runs windows (same hardware fresh installs windows with no issue). brand new ryzen 2nd gen with graphics.
 
I know about graphics drivers issues, wasn't expecting that to be dealt with.
Just trying to use it as a cpu. So I put in an older (RADEON HD 7850 pitcairn) video card to get some functionality.

Without the video card, it boots, but the display is unusable. I can ssh
in and see that it works fine as a server, but cannot use terminal or
graphical display.

With the video card, Put daily ubuntu Bionic image, and "Try Ubuntu",
and it goes into an infinite loop. photo attached.  I tried 16.04.4 and
I think it just went into a blank screen.

** Affects: grub2 (Ubuntu)
