I noticed the same problems and a few more. For example closing the lid hangs the system. Disconnecting the power supply hangs the system. All clearly kernel related.

I tried the iommu=soft solution which didn't work for me. Also adding amd_iommu=pt didn't help.

The best fix I found so far was upgrading to a more recent kernel. i.e. Get this script: https://github.com/pimlie/ubuntu-mainline-kernel.sh
And install the latest kernel.
