No. It's different.

and which one is the latest? kernel-smp#2.6.9-42.0.8.plus.c4 kernel-smp#2.6.9-42.0.8.EL or they're different kernels?

Different. As the "plus" implies, it's the default kernel plus stuff.

One can also consider the "plus" kernel as "unsupported", meaning is it not a direct translation of what you will find on the upstream distribution.

A small disagreement, with your permission: support for new hardware is sometimes added by RHAT to older kernels, in the first 2.5 years of a release.

Take the BCM5754 (0x167A) Broadcom NetXtreme Gigabit Ethernet Controller you can find in Dell Precision 390.

BCM5757 is supported (TG3) in the kernel only since 2.6.17-rc1. However, RHAT has backported the support for it in the 2.6.9 kernel, and it's currently available in RHEL4-U4 and CentOS 4.4.

Actually, RHEL4-U4 Desktop/Workstation is certified for Dell Precision 390, as you can find by searching hardware.redhat.com for bcm5754.

And this is not a bug fix, but a new feature.

I don't agree that is exactly a backport. More likely complying with the certification needs, which Dell pays for anyway.

I find it important to point the difference here because, otherwise, people might be led to expect other such backports, which won't happen unless someone is paying for it (Dell, in this case).

Even tho, technically speaking, it can be considered a backport.

kernel-smp#2.6.9-42.0.8.plus.c4

Stuff from the centosplus repo is centos-special extra stuff that does not exist in upstream (some stuff that are disabled in the normal kernel are enabled in the plus one). Generally, don't use stuff from centosplus if you don't have to (that's why it's not enabled by default..).

what's the extra stuff for the plus.c4? is there a site i can check?

thanks
