You may want to take a look at /boot/grub/ and make sure
it is correct. It is possible that until the OS boots, and loads its
own driver, that the drive is /dev/sda instead of what ever it is
called when the RAID is active. (From what little I know about
fake-RAID, it requires the proper OS driver to be loaded before you
really have RAID.)

Another possibility, but not one I would expect to run into with a
modern BIOS, is that the update moved the kernel, or the inital RAM
disk image, to a part of the hard drive that the BIOS can not
access. But if that were the case, I would expect the old kernel to
still boot. (This was why a separate /boot partition near the start
of the drive was used in the past.)
