This is an Ubuntu/Xen issue: some versions of Xen do not support threads properly. The crash is a symptom of something going wrong in the initial thread trampoline, which should never return.

Nothing SBCL can do about this, unfortunately. I recommend filing this as a bug against the Xen package you use.

As workaround, you can use a single-threaded SBCL instead. If you cannot build one your self, you can use for example http://random-state.net/tmp/sbcl-1.0.46.13-x86-linux-binary.tar.bz2.
