Could be, as I wrote earlier I don't know how to check this on a
Fusion or Megaraid chipset because all I have is
/sys/class/scsi_tape/nst0/device/scsi_level=4
/queue_depth=7
/queue_type=simple

The 53c8xx drivers are more verbose..

Actually I'm running a full backup (a few TB) on a generic 2.6.11.12
kernel with good performance (>30MB/s) on the LTO-3 tape library on
a 53c1030 controller. That's first priority. After that backup I will
play again with different kernel versions and the other tape library.

Sorry for that delay..
