This was safe, because the SATA driver re-enabled it. But with commit a5bfc471 ("ahci: drop intx manipulation on msi enable"), the driver no longer does this, and so SATA support on the 8610 HPCD is broken. The original quirk function disabled INTx because it caused some other interrupt problem during early development on this board, but no one remembers any more what that problem was, and it doesn't seem to occur any more.
