Lucid beta 2 changes data source disk drive during install

[Freebirth One]

Following cirumstances:
 * an old disused workstation which works as an domain server
 * happens to have two disk drives residing on the same IDE channel
 * both drives contain different Versions of Ubuntu CDs
 * what exactly the hardware is I can append later

What happened:
 * I tried to install from an Ubuntu Server 10.04 beta2 CD
 * the Boot-loader (ISOlinux?) shows the correct Options
 * after choosing "Install Ubuntu server" the Kernel is loaded
 * after that the Locales are questioned
 * the next screen has a red background and an error message like "ubuntu-server.seed not found"
 * changing to a shell and looking after it shows: only ubuntu.seed is there
 * altering the kernel call is just a small help; after this comes a message like "Data not found"
 * after that you cannot proceed with the install

The clue:
 * because I tried to rescue the former os (Ubuntu server 8.04) with an Ubuntu Desktop 8.10 this CD still was in oine of the drives
 * after I was booting the 10.04 beta2 from the other drive and the kernel was loaded, the data source switched to the drive with the 8.10 in it
 * naturally from there the data couldn't be loaded

reproducable:
 * yes, with the 10.04 Server and Alternate

the Question:
 * can anyone reproduce that? And why is this even happening?

The Solution:
 * after getting rid of the Desktop CD and having only _one_ CD in both drives together, the installation worked like a charm

my guess:
 * somehow crippled because of using two drives on the same IDE channel
 * I think, SATA would fix this automatically

This is one of my favortites: finding the strangest bugs without wating it :)

Is this issue still present?

No idea.

During this weekend I have the chance to test it with the lucid final; after that I'll new more :)

Until then please be patient.
