Looks like exactly the same issue affects 13.04 with 3.8 kernels. I have a system with OS installed on SSD and also it has a 2-disk 1TB RAID1 with data. After upgrading to 13.04 I've started to get a message about failed RAID on every boot like described in this ticket. The RAID in fact was not a failure. As a workaround I am forcing grub to boot into 3.5.0-34 kernel which does not have this problem. I noticed this problem with kernels 3.8.0-26 and 3.8.0-27.
