came across e very weird issue.
I mounted a CM3+ 8GB on a CMIO board using rpiboot on Ubuntu 18.04.
No I try to mount the same CM3+ using rpiboot on Ubuntu 20.04. But all I get is this:

Instead it works with another CM3+ which was bought some months ago. I get the same messages as reported above, but then it continues and mounts the CM3+ correclty:

Seems to be a bad combination of CM3+ batch and operating system.
