I have observed hangs after crash on a Raspberry Pi 3 Model B+ board
when a panic kernel is loaded.  

kdump is a best-effort thing, it looks like this is a case where the
crashed-kernel can't tear itself down.

Do you have the rest of the stack trace? Was it handling an irq when it decided
to panic?:

the Raspberry Pi 3 B+ support is very fresh (linux-next). Since i didn't 
see a version, i need to doublecheck.

You are actually using linux-next and not the downstream kernel?

Very good point. I'll try again with linux-next.

Stay tuned,
