Hello, xnu/bsd/ufs/ffs/ffs_vfsops.c:ffs_sync() contains ---------------------------------------------------------------------- /* * Write back each (modified) inode. */ simple_lock(&mntvnode_slock); loop: for (vp = mp->mnt_vnodelist.lh_first; vp != NULL; vp = nvp) { int didhold = 0; /* * If the vnode that we are about to sync is no longer * associated with this mount point, start over. */ if (vp->v_mount != mp) goto loop; ---------------------------------------------------------------------- As mp->mnt_vnodelist is protected by mntvnode_slock lock, which is not released here, offending vnode cannot be removed from the list, and goto loop is infinite. Exactly the same bug was present in the ffs_vfsops.c:1.232 (Fri Apr 30 23:14:30 2004) version of this file in FreeBSD, but is fixed in FreeBSD HEAD.
