slow UML on x86-64, soft lockups

Recent 2.6.18 / 2.6.19-rc kernels run at the expected speed, on 32-bit x86, with a Fedora Core 5 or 6 UML userland. However, on 64-bit x86-64 with a 64-bit UML userland, the kernel is achingly slow. It works, but... Login takes several minutes (via ssh from host or xterm console), and soft lockup traces continually print to the screen (see output below). Once logged into, programs work, but again, very slowly. Commands which complete in under a second normally often takes minutes.

Any ideas? I guess there is a bug in the 64-bit UML timer code?
