Is there anything in the output of dmesg that relates to the I/O error?

The /etc directory file may have an invalid block number in its block 
list, pointing past the end of the volume, for example.

I wouldn't try to make any modifications to the filesystem, let alone 
fully boot it, without imaging it first. You could very easily have a 
corrupted free block list that could cause boot logging to write all 
over the data you care about.

Your best bet might be just to do a reinstall.

IIRC, /initrd shouldn't even exist except during boot before swaproot; 
that's a transitory filesystem used to load drivers so the kernel can 
find the devices it needs. If it does exist it *might* mean that your 
last kernel patch had a problem building the new initrd and aborted, 
e.g. if the filesystem was full or if the RAID controller caused 
problems. You might have a previous kernel you could boot (should show 
up in your grub list), but as I say, I wouldn't even try to boot the 
system in its current state without making a disk image.
