    I have exactly the same problem with 2.4.2 (RH Linux 7.1 - IIRC)
    and IBM DTLA - 307040
    I think the problem is in VIA82CXX support in 2.4.2
    At least for vt8233
    With current 2.4.16 (and 2.4.17-rc2) my disk works realy nice (37-38 Mb/s)

    So I think you must get new kernel
    and recompile it with
    VIA82CXX support:
    > [root@xyz jfl]# /sbin/hdparm -d1 -X66 /dev/hda
    btw please use
    /sbin/hdparm -d1 -X69 /dev/hda
    instead (if you need UATA100)

    Best regards,
