I have just converted a 1.2 machine to 1.3Alpha and everything went very
well except the floppy drive no longer works, I get an error on bootup of

   fdc0: can't set up ISA DMA map

The floppy always worked fine on 1.2, and the exact same 1.3 kernel works
fine on another motherboard. Both motherboards are Intel Pentium-Pro, the
working one happens to be a Pentimu-II, the non-working is a standard Pentium-
Pro. What I suspect is that the large memory has something to do with it, the
working floppy is on a machine with 64Megs and the non-working is on a machine
with 256Megs of memory. The working machine has IDE drives, the non-working
has a large scsi drive, I don't thing this has anything to do with it.

Here is the dmesg output on the non-working machine:

Any thoughts on what might be going on here, I have added the following
entries to the config file but it didn't help:

options         NKMEMCLUSTERS=2048      # slots in kmem_map
options         NMBCLUSTERS=2048        # slots in mb_map

Am I doing something wrong or is this a bug?
