Random i/o errors on good drive after Lucid upgrade

[Castarmax]

Hope these are the logs thats needed and that Ive posted them in the proper manner.
Problem is I'm having random i/o errors and the system freezes after I upgraded from 9.04 to Lucid
Here is part of my syslog and the others are large so I compressed them.

1. Upgrades are always problematical, save your data and do a fresh install.
2. People are not goings to trawl through masses of log files to try and find your problem, you provide some specific things and then you might get some useful ideas.
