Description Peter Chadwick 2021-02-21 17:10:11 UTC
Leap startup stops with:
"Error getting iommu info. ist the iommu enabled?"
"Error initializing iommuv2"

Hardware is AMD Ryzen 5 3400G on an ASRock B450M based motherboard

It's possible that Leap15.2 / SLE15-SP2 kernel still miss some support for the recent AMD platforms.  Leap15.3 / SLE15-SP3 should work better in this regard.

In anyway, please give more details.  The full dmesg output and the output of hwinfo would be helpful.
