I would like to provide additional information. Problem is that dumpdev="AUTO" gives the message that no suitable dump device was found. Full disk encryption is set. Swapinfo gives location /dev/mdxxxxxxxxxxx and partitions seem to be listed in /dev/ as ad0p1, ad0p2, ad0p2.eli. Can you please advise how to set dump device?

^Triage: I'm sorry that this PR did not get addressed in a timely fashion.

By now, the version that it was created against is long out of support.
Please re-open if it is still a problem on a supported version.
