Cough. You are missing a boat load of crucial fixes. There is a damned
good reason why 3.0.stable got 12 updates and the -rt version 14.

I don't doubt there are.  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
