I don’t know of a test suite as such but if it can’t reliably boot a
Linux kernel from known-good storage (e.g. fresh install on a uSD card)
then you’ve got the core of your answer: it’s broken.

As others have said, SD card failure should be right at the top of the
list of possible causes.

“Processes reporting errors” is harder to assess with so little
information, certainly there’s not enough presented here to assume a
hardware fault.

Fuzzing is a technique for discovering bugs you didn’t yet know
existed. In this case it seems you can already reproduce the issues...
