Userspace segfaults or kernel oopses ?

If you're seeing kernel oopses, those appear to be due to some
Athlon chips faulting on prefetch(NULL) even though prefetch is
defined to never fault.

Also, it only faults under some circumstances, which we haven't
quite pinned down yet and only only on some Athlon steppings
(we haven't exactly pinned down this either).  The kernels in
the Taroon up2date channel have a workaround.
