As I wrote, I made new test on kernel Linux version
5.1.0-050100-generic amd64:

Same problem, system crash after a few seconds. Full kern.log: https://paste.ee/p/EmLsw
Most helpful. First, try to replicate this with the iommu disabled.
Secondly, make a proper bugreport mentioning the affected kernel version (5.1)
Thirdly, if possible replicate this with the vanilla kernel from kernel.org
Unfortunately, I can't judge if the patch is there, but
I found, that this patch was added to kernel 5.0.2:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/iommu/amd_iommu.c?id=4e50ce03976fbc8ae995a000c4b10c737467beaa
Can I somehow
verify that the patch is in this ubuntu kernel 5.1.0?
You would need to look into the kernel source, but this is not necessary.
Joerg's guess was incorrect.
