The only change I can think of that might affect this controller is that
auto-pause is now enabled for 7880 controllers.  To verify this, please 
change
line 250 or sys/dev/aic7xxx/aic7xxx.h from this:

        AHC_AIC7870_FE  = AHC_TARGETMODE|AHC_AUTOPAUSE,

to this:

        AHC_AIC7870_FE  = AHC_TARGETMODE,

Can you also send me the output of "pciconf -l" using a kernel that boots
as well as any markings on the main chip (sticker and what's underneath)
from "ahc0"?  I somehow doubt that it is a 398X, but that is what the
driver thinks.
