Hi Matthew,

So  what  can  be  done about it? I don't really have much of a choice
here - controller is integrated with backplane/motherboard and there's
no  way  of  swapping  it out. Just tested it in 9-CURRENT, but as you
probably already figured out, without much of success :(

Just for clarification: motherboard is Intel S5520UR, preinstalled in
Intel SR2600URLX chassis.

Any pointers will be much appreciated.
