After applaying the next patch I can now see
in dmesg output:
........
ad4: 19574MB <IBM-DPTA-372050> [39770/16/63] at ata2-master tagged UDMA66
ad6: 19623MB <IC35L020AVER07-0> [39870/16/63] at ata3-master tagged UDMA66
.........
This configuration (ad6 is the IBM's Deskstar 60GXP(?) series
disk) was 'tested' by the 'make -j32 buildworld' with the /usr/obj
on the ad6 disk.
Does this mean that this disk really support "tagged queueing" ?
Is there any way to test/demonstarte this ?
