For further investigation, I would like you to give some instructions
about the way to use OpenSUSE distribution. I want to boot the distribution
in 'low graphics mode' which debian/ubuntu distribution has. In the mode,
I expect to boot it without loading amdgpu module which depends on iommuv2
module.
Anyway, I would like you to check reporters' chipset when the similar
issues are reported. If they encounter the issue still in Intel chipset,
please inform it to me, since it could deny my current presumption.
