YD3: Startup fail, kernel access of bad area

[Igor P. MERKU']

Hello,
does this (see following between snip/snap) during startup of the first 
CD:

------------snip--------------
Oops: Kernel access of bad area, sig. 11

mean, my machine (NewWorld iMac) has a hardware problem? Like RAM?
(I tried all the install CD images I found up to the latest, May 30th)

Best Regards and Have a nice day,
Igor
