I had a much similar problem. The cause is the floppy driver doesn't wait
for 'master' to be ready. The changes are as follows:
lines 2853 must be loop that waits for the master to become ready, optionally
using a time-out or a specific number of iterations, e.g:
	i= 0;
	do {
		port_in (FDC_STATUS, &status);
		if ((status & MASTER)==0) i++;
		else break;
	} while (i< LOOPCOUNT);
	if ((status & MASTER)==0) return (ERR_STATUS);
	....
