This usually means that the maddr is wrong or that the hardware is not
there for some other reason.  A normal hex dump of cyclades isa memory
looks something like this
(output from "dd if=/dev/mem bs=1 iseek=0xd4000 count=0x2000 | hd"):

Values at even offsets are always repeated at the next (odd) offset.

CD1400_GFRCR is at offset 0x80 (contents 0x46 in the above).

The abort is a bit unusual since the cyclades probe is not very invasive.

I think mine is much older (model 8Yb).

Did you say that it worked under old versions of FreeBSD?
