Looks like an H310. I just booted an R420 with such a card into -431.17.1 and it works just fine. Here's the lspci -nn data: 

01:00.0 RAID bus controller [0104]: LSI Logic / Symbios Logic MegaRAID SAS 2008 [Falcon] [1000:0073] (rev 03)

The previous kernel version boots fine and everything works just well, but the latest kernel (v2.6.32-431.17.1.el6.x86_64) cannot boot and Grub says something like "trying to reach blocks outside of partition" and that's all the message there is and boot hangs.

The size is 1.8 TB (2 x 2 TB disks in the array, the raid BIOS of the card does not show any problem). I've got plenty of free space and should not be at the limit of the inodes either I believe. Also, I entirely reinstalled the kernel thinking that something could have gone wrong during the update, but it gives the same result.

It really seems Grub has trouble with your /boot. Maybe due to a filesystem inconsistency. Maybe due to a large inode number it can't deal with (does "ls -i /boot" reveal anything unusual?).

Cheers,
