Could there be a problem with using logical address 1?  ISTR that LA's map
directly to interrupt vector numbers, and most processors tend to reserve
the lower numbered interrupt vectors for other things (I don't know what
CPU is used in an hkbaja60 though).  Try switching to a logical address
above 0x40

I'm not sure whether that would explain these symptoms or not though, it
might just mean that you couldn't connect an interrupt routine to that
card, or it may be that it's only the MXI modules that have that
restriction.
