Here is Adaptec's response: ----
The OS that you are using is not supported by this controller card.
The standard Fedora Core 2 kernel 2.6.5 , should though allow you to install, but Ralph there are I/O errors reported under heavy loads.
The newer 2.6.7 and 2.6.8 killed the aacraid completely are non-functioning as well.
I 2.6.9 (FC3) has not tested yet.
Driver and controller support is not provided for Fedora.
Changing motherboards and RAID type could definately have an impact on whether or not the installation was successful.
----
I don't know who Ralph is but the message is clear. This is not a good card for FC3. Based on my apparent success with the first card I purchased two more. All three will live on my shelf for the forseeable future, and I will order a 3Ware 8506-4LP to see how that works.
I hope this message saves somebody else the considerable aggravation that I went through with the Adaptec cards.
Frank.
