We got the i20 driver update from Adaptec's site, THEN updated RedHat's
kernel using their up2date utility.
Here's the steps:
1. Have your SCSI Raid driver disk ready
2. You need to reinstall RedHat in expert mode so it will *not load* the
default redhat driver for your RAID (this was part of the problem).
3. Insert the SCSI Raid driver when it prompts you
4. Install Linux as necessary
5. As soon as your install is finished, run rhn_register, and up2date to
download the latest kernels for your machine.
6. Install and run Postgres
These are the steps that we used with success.
