Check the logs. My guess would be that it is a peripheral problem and
initramfs conflict. Check your fstab and grub as well to make sure the
drive & CDRom are properly configured.

_If_ it boots to an older kernel, it could be that intramfs isn't
getting updated for the new kernel. You could try:

sudo update-initramfs -u -k <kernel>
sudo update-grub
sudo aptitude reinstall linux-restricted-modules-<kernel>

Example: sudo update-initramfs -u -k 2.6.24-12-generic
sudo update-initramfs -u -k 2.6.24-12-generic
sudo update-grub
sudo aptitude reinstall linux-restricted-modules-2.6.24-12-generic

If the inintramfs script didn't get generated for some reason, then make
one first:

sudo mkinitramfs -o /boot/initrd.img-<kernel-generic> <kernel-generic>
sudo update-grub

See man update-initramfs. Using the -u just updates. If you want to
create a new one then use -c.
