But we've only experienced one problem between 3.0.36-rt58 and 3.0.48-rt72. Indeed, it might be easier to evaluate the risk if all the changelogs were readily available. So far, however, we haven't discovered any other issues that give us any concerns. > Your risk assessment is definitley interesting. We have specifically tested 3.0.36-rt58 for performance in our application. Moving to 3.0.48-rt72 poses risk about whether would still be able to meet our performance requirements. And with regard to stability, the only issue we've had since our earlier moved to 3.0.36-rt58 was the netfilter problem. We initially only saw the problem on PPP related interfaces, so we reverted to 3.0.3 (non-rt) for PPP related issues. Now, if you think there are some issues that should raise eyebrows, or can point me to a list of changelogs, I'd be happy to evaluate them. Thanks, Pete
