[Bug 1872452] Re: [amdgpu] Boot into black screen without power supply (Kubuntu on AMD)

[Neil]

I've managed to get the system to boot when not plugged into mains by
adding 'iommu=soft' to the linux line in grub.

Not sure at what cost but at least I don't lose my display info like
when nomodeset is used.
