I'm seeing this problem now. For me it only started occurring after upgrading MAAS from 1.5+bzr1977-0ubuntu3 to 1.5+bzr1977-0ubuntu4. MAAS is no longer able to PXE boot.
To rule out any upgrade/configuration concerns I purged and reinstalled MAAS (wiping out the database, all configuration files, downloaded ephemerals etc. and essentially going again from scratch). This landed me in exactly the same situation.
