This issue has been SOMEWHAT resolved in the final release. On the first of two tries with a CD-ROM burned from the ISO that I downloaded on Apr 29, 2010, the machine booted nicely, I checked the disk for errors (none) and then entered into a Live session without any problems whatsoever. However, I had to reboot halfway through system testing because of a failure of video modes that I don't normally use. On second reboot from the CD-ROM I waited through the timeout and thus went directly to the Live session. The unrecoverable message DID appear, but that did not stop progress into the live session.
