This didn't used to happen. I believe it started with the 3.11 kernel
since there is new code in that area. I will try installing 3.10 and
some early 3.11 RCs and see where I land.  I know where to get the
earlier kernel packages (kernel team PPA) but how do I interrupt the
boot process to tell ubuntu to run an older release. Everything is
masked by the "Ubuntu" logo boot now.
