Sorry, I have not tracked what causes hangs after kernel is loaded,
but it seems there are some other problems.

Hmm, 512(bytes) * 80(cyls) * 2(heads) * 18(sectors) = 1474560,
so it should be fit a floppy. What machine did you tried to
write the image? It seems there is no device file for fd0a
under /dev and just your root file system is filled.

It seems there are some spurious interrups. How about the workaround
mentioned in news68k FAQ?
