Things to try that are unlikely to break anything any worse.

Boot the rescue CD, chroot to /sysimage then

Make sure /etc/modprobe.conf has an alias line for megaraid_sas.

VER=`uname -r`;/sbin/mkinitrd -v -f  /boot/initrd-$VER $VER

grub-install

If it's getting to stage2, the grub-install is probably superfluous, if
you have time, you might see what results you get from just rebuilding the
initrd.
