The calls set_thread_area(2) and get_thread_area(2) are not implemented
in UML.
Both are essential to NPTL. There may be other problems too...
Implementing them gets really tricky if you want UML to work with a
2.4.x host.
I've been trying to steal enough cycles to learn enough to just
implement them on a 2.6.0 host.
