Could somebody that is seeing this problem try to boot with kernel flag "iommu=off". Some hardware that used to work with older kernels may be broken and fails to work with modern kernels which default to using IOMMU.

Note that disabling IOMMU is a heavy handed workaround, not a proper fix. For more information about IOMMU, see https://heiko-sieger.info/iommu-groups-what-you-need-to-consider/
