Yes, that's a known problem.

You might increase the journal size to allow for larger transactions
with the tunefs command. But there is still a limit that you could
hit.

"device bad" means an ENXIO error from the device driver.
There could be several reasons for that, but I'd guess
that the partition isn't typed as "swap" or "raid".

The swap code ignores the type, but the dump code does not.
