   Hrmmm.. on further research, it appears to not be an exception vector,
but instead register storage of the last program that violated
the memory alignment access rules.

  Anyone want to correct me ?

    Hrmmm.... I see in the archives when the initrd was fixed, for an ES20

  Is this SMP kernel from the upcoming Alpha Core, or the existing one ?
