Do you get this error repeatedly? Because it does not look like a hardware 
problem to me, it's probably more a filesystem corruption. And from your 
log excerpt it seems to have been fixed. You can force a fsck at next boot 
to be sure (shutdown -r -F), but it's probably more a software error than 
a hardware one.
