But I am seeing -ENOSYS from one of [gs]et_thread_area right before things go haywire. But I haven't looked at it closely enough to see if that's the real problem. 2.4 UMLs work fine with these libcs. I had been assuming (without any evidence) that there was some other capability check (like uname), and libc gets horribly confused when it sees a 2.6 kernel that doesn't have the thread_info stuff. If the compatibility check is -ENOSYS from one of those syscalls, then this theory goes right out the window, and something else is wrong in UML.
