Sii3114 bug ?

Setup:

a1-se, sii0680 sii3114, wd 80 gb pata hd, st 120 sata hd , plextor px-712 sata dvd/rw.

sata hd is in port1 (first port), dvdrw in port 3. Mtb reports id 0 to hd and id 3 to dvdrw. If i plug dvdrw to 2nd port, mtb report id 2. If i plug dvdrw to port4, boom, no dvdrw. Same applies to hd. So port 4 is inaccessibe/unusable.

again and clearer:

sil3114 port mediatb id
port1 id0
port2 id2
port3 id3
port4 nothing



sometimes,when I boot, sata hd is not found at all. Dvdrw is allways there. Exept if plugged to port4.

broken sil3114 or bug?
