Red Hat hangs
I run Red Hat 7.3 on an IBM Think Pad laptop. Its been running fine but lately I have noticed a problem. Every so often, it stops responding (hangs) and I am forced to switch it off and back on after which it does not see the network adapter and I have to restart it to get it back on the network. My mouth gets dry when my colleagues start asking what's happening to my new 'stable' OS. I have no idea where to check and why it could be doing this. Someone please help.
