9.1-RC3 reproducible kernel panic in ffs_valloc?

[CeDeROM]

This problem was caused by corrupted UFS2-SU+J (9.x default) filesystem
marked as clean where journal showed no issues, running fsck -t ufs -fy
solved the issue!

I guess filesystem related kernel panic should enforce full filesystem
chceck (some filesystem flag or journal date modification to enforce full
check).

Maybe it is possible to stop the OS in that case, perform some sort of fsck
running from memory, and then continue the OS with no crash? :-)

Best regards :-)
