I have extracted material from the list-exchanges related to this and submitted:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220693 against the kernel for the issue. I placed emphasis on the SSD-trim related "freeing free block" panics that "fsck -B" can lead to after it gets the g_vfs_done messages for unclean ufs file systems but first noted that: mksnap_ffs /.snap2 was enough to get the g_vfs_done messages. I figured that the nastiest and most important known consequences were "fsck -B" being broken for unclean ufs file systems and having later panics trying to trim based on how it is broken. I did also mention dump as producing the messages.
