The following reply was made to PR kern/122380; it has been noted by GNATS.

I have many ffs partitions (40) and am running a simple load generation script against each mount point. The load generator just does a random collection of create, read, write, hardlink, trunc, delete from a script. There is only a single application thread running against each mount point, but there are 40 processes running against 40 different mount points. This has happened both after a hard crash + FSCK, and fairly soon after a newfs. 36 of the devices are SAS drives. 4 are SATA SSD. I'm not sure which mount point is involved, yet.
