In kern/42277 it looks like something is stomping on inodedep->id_inoupdt and setting it to 0xffff0000, probably while other kernel code is executing and before this struct inodedep was looked up by inodedep_lookup() at the beginning of softdep_update_inodeblock(). I don't think the list pointers are getting corrupted because that would show up differently in worklist_remove() and worklist_insert() because of the amount of list pointer dereferencing done by the underlying LIST_INSERT_HEAD() and LIST_REMOVE(). It looks like the list head itself is getting corrupted. Offhand I'd say this problem could be just about anywhere, and will not be easy to find.
