At first, I thought this was somehow related to the 2nd CPU being fired up, but
after looking at /var/log/messages I doubt this is it.  It seems that the long
delay is somehow related with the system trying to mount the SATA drive (ads4a).
What is strange is that: a) A SATA-300 drive/controller are seen as SATA-150 and
b) That the floppy drive goes active during this long pause as the system "hunts"
to mount the drive.

Does any of this make sense to you hardware/driver geniuses out there?  Other than
these two boot-time problems, the system appears to be stable and work well.  I'm
just concenred I have to way during each boot and am not able to get full drive/controller
performance.
