Dear Giovanni, thank you for reporting this bug and helping make Ubuntu better.
Ok, so you can boot with kernel version 2.6.24-18 but not 2.6.24-19. We are going to need to know the hardware included in your system, and any error messages the kernel issues. Booting the working -18 kernel, please run the following 4 commands, and attach the resulting files. * uname -a > uname-a.log * cat /proc/version_signature > version.log * dmesg > dmesg.log * sudo lspci -vvnn > lspci-vvnn.log It would also help to know any error messages from the -19 kernel. In /boot/grub/menu.lst, you don't need to comment out the -19 kernel, just change the "default" option (right at the top) from 0 (1st kernel in the list) to probably something like 2, which should be the -18 kernel (3rd in the list). Then try booting the -19 kernel without the "quiet" and "splash" options, and tell us any error messages you see (taking a screenshot with a digital camera, or even writing them down by hand and typing them in here is also fine...
