Bug Description
I downloaded the 'live' CD images of the daily 32-bit and 64-bit Ubuntu Intrepid Ibex builds from August 23, 2008.
I burned the images to CD.
I tried using both CDs on my two home desktop computers which each had an Adaptec PCI SCSI controller installed.
Neither CD would boot up with an Adaptec PCI SCSI controller installed, but both computers would boot up with no error messages when there was no Adaptec PCI SCSI controller installed.
I assume this is a problem because Ubuntu does not tolerate the on-board BIOS on PCI SCSI controllers but I have no prior knowledge of Ubuntu (or linux in general).
I downloaded the 'live' CD images of the daily 32-bit and 64-bit Ubuntu Intrepid Ibex builds from August 26, 2008, with similar results.
I downloaded the 'live' CD images of Debian Live Lenny Beta 1 and they would not boot up with the Adaptec PCI SCSI controllers installed either.
I downloaded a 'live' CD of OpenSUSE 11.0 and it would boot up with the Adaptec PCI SCSI controllers installed so I assume the problem is peculiar to Ubuntu and Debian linux distributions.
The screens that result when booting up Ubuntu Intepid Ibex builds with an Adaptec PCI SCSI controller installed are as follows:

Additional information: The PCI SCSI controllers are only used for A3 size flatbed scanners with SCSI interfaces, Microtek ScanMaker 6400XL and Epson GT-10000+. I do not own any other SCSI devices. The referenced failure to boot a live CD occurs consistently regardless of whether or not the scanners are attached to the PCI SCSI controllers.
