Hello, Thank you for testing, and for all the others who have tested. I am not sure why cpuspeed it isn't failling on a CentOS machine, but there have been several tests on pure SL machine's. I also was able to find a machine to do some tests over the weekend and gave it a wide battery of tests. I think the most important test was that installing the newer cpuspeed doesn't break anything on the older kernels. That was my biggest concern. So I will be pushing out the newer cpuspeed out today into the security errata. It is marked as a security errata because a real security errata has a dependancy on it.
