https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236504 --- Comment #13 from commit-hook@freebsd.org --- A commit references this bug: Author: mckusick Date: Tue Aug 6 18:10:34 UTC 2019 New revision: 350651 URL: https://svnweb.freebsd.org/changeset/base/350651 Log: A race condition existed between the time a UFS/FFS superblock check hash was computed and the time that the superblock was copied to a buffer to be written to disk. The result was a failed superblock check hash the next time that the superblock was read. The fix is to compute the check hash after the superblock has been copied to a buffer to be written.
