I have installed OpenBSD 6.9 onto the tested RPI4B-2GB today to see if the version change causes any issues, and so far it seems to be working without issues. If it goes well, I am going to move the USB storage to the previously tested RPI4B-8GB in a few weeks. If that does not result in the error, it will be reasonable to presume that the issue is specific to USB 3 or some specific workload your board is trying to run. -- Denis Ovsienko
