The sata module creates devctl node with wrong minor number:

909    ASSERT(ddi_get_instance(dip) <= (L_MAXMIN >> INST_MINOR_SHIFT));
910    if (ddi_create_minor_node(dip, "devctl", S_IFCHR,
911        INST2DEVCTL(ddi_get_instance(dip)),
912        DDI_NT_SATA_NEXUS, 0) != DDI_SUCCESS) {

Instead of INST2DEVCTL() macro there had to be used SATA_MAKE_DEVCTL_MINOR(). This causes confusion in sata_devt_to_devinfo() and then also in sata_hba_open(), sata_hba_close(), and sata_hba_ioctl() respectively.

Examples of wrong minor numbers:
