This sounds like a user configuration error.  The adaptec has a bus
settle time in its initialisation path.  Originally it was 20s, hence
for a D card (twin channel) it would take about 50s to come online
(extra 5s to scan per channel).  There was a lot of argument about this,
and the value was finally made configurable as

CONFIG_AIC79XX_RESET_DELAY_MS

I suspect you have this set to around 15000.  You can make the boot
sequence shorter by reducing this value.  I believe Red Hat configures
it down to the default 5000.
