After upgrading from 5.6.14-1-default using `zypper dup` I couldn't boot and
had to boot with the old kernel. The issue happened in two subsequent minor
versions.

Reproducible: Always

Steps to Reproduce:
1. Upgrade from 5.6.14-1-default
2. Restart machine
3. Select 5.7.1-1 or 5.8.4-1 on grub
Actual Results:  
 - Loads initial RAM disk
 - mentions IOMMU errors (happens with previous kernel too)
 - boot freezes
 - second screen isn't activated (that's how I know it's frozen)

Expected Results:  
 - Loads initial RAM disk
 - mentions IOMMU errors (happens with previous kernel too)
 - activate second screen
 - show splash screen

I cannot test with patch version of 5.6.x since Tumbleweed doesn't provide them
anymore.

`journalctl` doesn't have any logs of the failed boots. It doesn't seem as if
it gets that far, but I'd be happy to try and get debug logs if instructions
are provide on how to do so.

My camera is trash (thank you OnePlus) so, I'll jot down the logs before it
freezes and post them later.
