I'm pretty sure I fixed this last year in these:

commit 1a69e2ec5e039379e7ce5c457bff4c5194177d34
Author: Mateusz Guzik <mjg@netgate.com>
Date:   Wed Mar 5 15:37:48 2025 +0000

    udf: manage si_mountpt

    Prevents panics when the device is already mounted by ufs or msdosfs.

    Note: the code remains buggy in other ways by failing to clean up after
    encountering bad options.

does the issue persist?
