In general, trying to figure out what is happening at the kernel buffer layer by watching `cp` results and A20 will be very complicated, since most application I/O is performed...

How about with hma=kernel #xms=on #xms=int15 Does everything work without error? This would indicate that LOADALL XMS code may still be faulty in peculiar way.
