My advice, is kinda silly, but, Mathieu Desnoyers is saying use a newer version, and the version you are using is not working, I would at least try out a new version.
What kernel are you using? If you're on 2.6.16 We actually got it +- working with UST 0.12. git://git.dorsal.polymtl.ca/~mattkhouzam/ust_documentation Note: you cannot tell which core is being used if you apply the changes in the document, so if you are using a multi-cored cpu, you really really should consider updating your kernel.
