That 64kB block size problem is a quite old bug... etc at fluffles.net reported it
some months ago... It is somehow due to memory fragmentation and a dead lock...

a memory disk (md) should never deliver an EIO (5)... So u must have done
something different, than just reading/writing to/from a md...

But u can take a look at the source code and search for "EIO"...
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/md/md.c

A possible cause for that EIO is, that the file system parameters r somehow
bad, so that it reads from negative or too large offsets...

if (bp->bio_offset > pp->mediasize)
			return (EIO);
