I've got this controller, from dmesg:

  ahcisata0 at pci0 dev 17 function 0: vendor 1002 product 4391 (rev. 0x40)

or from pcictl list:

  000:17:0: ATI Technologies SB700-SB900 SATA Controller (AHCI mode) (SATA mass 
storage, AHCI 1.0, revision 0x40)

The reports from the previous links say SB710 and SB750 chipsets.

I _think_ the problem is restricted to 860 EVO drives, not 860 PRO drives.
