Hi Jeff,

   Even though libata sets  sdev->use_10_for_ms = 1;
libata still receives MODE_SENSE(6) and MODE_SELECT(6) commands during the test.
(These commands seems to be coming from the user space, not from the SCSI mid-layer.)

Most ATAPI devices don't like it, and either return error or time out.
(Ex.
Attached scsi CD-ROM sr0 at scsi7, channel 0, id 0, lun 0
ata7: command 0xa0 timeout, stat 0x50 host_stat 0x1)

Should MODE_SENSE(6) / MODE_SELECT(6) emulation be added to libata
to fix this? This can also make the ATAPI devices look more like real SCSI devices.
