I had the system running under ubuntu 9.04 server for 1 month without ever seeing this, it wont run an hour without this issue now. Currently trying to find my 9.04 disk so I can just go back, I need this thing online by wednesday. I wish I could have easily gotten more information for everyone, this is a huge problem for people with my setup. I think its possibly a controller driver thing.
