The status of the Ubuntu patch upstream, as best I can remember it, is that they think it's fixing the problem in the wrong place. The libc dynamic loader is meant to have some special magic set aside so that at least some TLS code with the initial-exec class can be loaded, but this clearly isn't working properly.
I started investigating this, then got busy with other things.
