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.
