I've got this panic once when copying a couple of files.
The system is stable/13 as of 1996360d7338d, a custom kernel configuration, but
no local source code modifications.
Unread portion of the kernel message buffer:
VNASSERT failed: ({ seqc_t __seqc = (_vp->v_seqc); __builtin_expect((__seqc &
1), 0); }) not true at
/usr/devel/git/trant/sys/contrib/openzfs/module/os/freebsd/zfs/zfs_acl.c:1147
(zfs_acl_chown_setattr)

Any ideas, suggestions, hints?
Thanks!
