No, if you want to remove the panic the printf should stay
I you get in this situation while running on real hardware, at best the
hardware is not recoverable, at worse it can misbehave bad enough to damage
some other memory region. A message on the console is mandadory, and a panic
looks appropriate to me in this case.
