  ^^^^^^^^^^^^^^^^^^
   This is your problem. There have been a number of bug-fixes to the
SiI drivers since 2.4.20. Try it again with a newer kernel -- such as
2.4.24.

   Not so. I have a SiI3112 controller and a 120GiB Seagate drive, and
they work very well together. I'm using 2.6.1, although 2.4.23 also
worked well for me.

   Try using 2.4.24 or 2.6.1.
