We're going to need more information to diagnose this.

And linux-ide should have been at least CC:'d from the very
beginning.

>From what I can discern the problem is introduced somewhere between
2.6.27 and 2.6.31, you have a Serverworks CSB5 and primarily the issue
is that attaching or detaching your CD-ROM driver influences whether
both of your disks are properly detected. Correct?

You seem to have played around with using the IDE layer vs. the
ATA layer. Can you see any difference in behavior if you try
using just the IDE layer vs. just the ATA layer with the 2.6.31
kernel?

Thanks.
