  Thanks your reply Tejun, i would try it  ^__^.

  Before that, Could i ask a question that had you ever try to using
port multiplier(sil 3726 or marvel 4140) with 6121/6145
succefully(with ahci.c) ?

Eh.. another mistake by me.  I was talking about controllers supported
by sata_mv.  Mark Lord worked on it and added PMP support.  AFAIK PMP
support on 6145/6121 is yet to arrive.  Right, Mark?

..

I have exactly zero documentation on those chips,
but they are supposedly AHCI compliant.

Looking in drivers/ata/ahci.c, one can see that the chips are indeed supported,
and there the AHCI_HFLAG_NO_PMP is *not* set, so one might expect them to work
with a port-multiplier already.  ?

Cheers
