Hypothesis about what's going on here. At some time in the past, something, i.e. dnode_reallocate() calls one of: dbuf_rm_spill(dn, tx); These will do: dbuf_rm_spill(dnode_t *dn, dmu_tx_t *tx) dbuf_free_range(dn, DMU_SPILL_BLKID, DMU_SPILL_BLKID, tx) dbuf_undirty(db, tx) Currently dbuf_undirty can leave a spill block in dn_dirty_records[], (it having been put there previously by dbuf_dirty) and free it. Sometime later, dbuf_sync_list trips over this reference to free'd (and typically reused) memory. Also, dbuf_undirty can call dnode_clear_range with a bogus block ID. It needs to test for DMU_SPILL_BLKID, similar to how dnode_clear_range is called in dbuf_dirty().

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
