We've had some trouble booting with the non-free AMDGPU graphics 
cards before, but the ‘AMD-Vi IOMMU’ part is new to me.  What 
exactly happens?  Which error messages (if any) do you get 
(pictures are fine, but please compress them to a few 100k or host 
them elsewhere)?

We can certainly try, if we know what (kernel CONFIG_ option, 
kernel command-line option, …) is required.

Since you seem to know more about the bug, could you explain it in 
more detail of provide a link to more information?

Thanks,
