OpenSUSE 11.2 server, Gigabyte GA-MA790X-UD4P
SATA: Promise EX-8350 [sda RAID1 for NOS] [sdb RAID1 for data]
SCSI: Adaptec AHA2940UW SD-M1401 DVD ROM & SONY SDX-500 tape drive

SCSI CD/DVD ROM reads CDs & DVDs fine as a data source, however when booting from a CD/DVD the result is a hang after the initial read. For example:
OpenSUSE 11.2 install DVD boots to the welcome screen, waits for my selection, displays “Loading Linux Kernel” then stops with a black screen & flashing cursor. Knopix had the same result. Gparted started to load but terminated with a screen full of textured symbols. Ultimate Boot CD for Windows inspects the hardware but never proceeds, Windows XP install CD did the same.
Here’s the kicker: Remove all SATA hard drives and the CDs/DVDs boot just fine. Must be a hardware conflict.
As part of my diagnostics I tried a SATA DVD drive and all booted fine. Yes, I could dump the SCSI DVD ROM, but I’d rather understand the problem and resolve it.
Thoughts or suggestions?
