could you please specify the exact kernel versions you are referring to? 
I'm not sure which version update 3 was. We are currently running 
2.4.21-15.0.3.ELsmp. We can't really use a newer version, because we need 
IBM's sdd driver for SAN vpaths and they are slow in certifying new kernels 
... maybe telling them about specific issues might speed up the process.

We haven't really had problems like the ones you are describing, but we 
have one where the loopback interface gets stuck. All RedHat has to say 
about that is to try the most recent kernel, of course.

Thanks, Sebastian Hagedorn
