Congratulation. And yes, the system feels much faster with nvme. 
Since you write “behaving well enough”, my question is, whether you get I/O problems with the nvme? Unfortunately, for now, i’m so plagued by it, that i cannot make the system self-hoisting.
Can you please try to git clone https://github.com/starfive-tech/VisionFive2.git?
Since there are only very few notes about NVMe I/O timeouts, i wonder, if it might is a local issue that only pesters me.
