I had a very similar problem a couple of weeks ago.  It turns out that the
Markfile in the ioc directory had ARCH defined for mv167 rather than mv162.
It was thus booting the wrong version of vxWorks, not a pretty sight.

I also have had problems with:
    - Boards not seated completely
    - The APS A32Vme module (position monitors, etc.) had problems on the
      mv162, probably because the default base address doesn't work with the
      162 BSP.
