I also have the same problem with Ubuntu 6.06 but on a Acer TravelMate 529 TXV. Booting stops as it tries to load the cd-module. The same thing happens when I try booting Kanoptix 2006 RC4 openSuSE and Knoppix are booting fine, with no bootoptions. -- Kernel Won't Boot on an IBM Thinkpad R30 https://launchpad.net/bugs/36998
