Public bug reported:
Binary package hint: libatlas3gf-sse2
Recently I upgraded to Jaunty (Ubuntu 9.04) and libatlas3gf-sse2
(3.6.0-22ubuntu2) stopped working. I found the problem with the python-
scipy package (linalg.test failed in TestCgemv). But it can be verified
with the libatlas-test as well:

The CPU is definitely capable of SSE2 so I do not see why this should
not work any more. It has been working with Intrepid before.
