Alright, so at least for the problems I have _today_, I've figured it
out, and the problem is that the watchdog test fails too quickly:

I thought it was the escape sequences confusing the check rather than
the platform takes longer than expected to provide whatever the expected
string is. Another TI K3 platform gets slightly farther along before
failing the same way. I'm going back to looping over Pis to see if they
fail in a way that they used to in my previous lab setup.
