Hi,
Usually I'm not one to complain about "old" version of the CentOS kernel and/or software, since I appreciate CentOS' stability. So this might be the exception that confirms the rule. I've been jumping through several burning loops these past days to configure my little MSI Wind netbook, and I'm currently considering going for a more recent kernel. There's no way the Ralink driver for the wireless card will build on an older kernel than 2.6.22, apparently.
I'm prepared to do some tinkering, but in the meanwhile, can you give some basic recommendations or caveats? This is not our production database server, so it's not a big deal if it's a little bit less stable.
What i naively plan to do: get a kernel SRPM from Fedora 9, try to build from there, and see where it leads. I think I'm going to give it a shot in VirtualBox first. But then, maybe one of you has already gone that path and can tell me if I have to expect something trivial or an experience of the hair-pulling type.
Cheers,
Niki
PS: with similar requests, folks usually suggest I run Fedora. So let me state: I like CentOS. I don't want to run Fedora.

It's not the end of the world. I've a server with a whole bunch of various services, running CentOS 5.2 x86_64 and a custom kernel, because the network card is not supported by the original kernel. It's rock solid.

Nah. Get the vanilla kernel tarball. Apply the mkspec patch. (*) Get the .config file from the CentOS kernel (see /boot). Use that config file to do a "make oldconfig" in the vanilla kernel source tree. This will import most settings from the original CentOS kernel. Now do a "make menuconfig" and peruse the config items. Make sure it's not missing important stuff. Now do "make rpm". Voila, you've got a kernel rpm that's pretty similar to CentOS, only newer.
(*) - without the mkspec patch, the rpm will be pretty generic. The CentOS/Redhat kernel rpm has a few more features that you need. This patch adds them. See the file attached to this message.

Now do this:
export RPM_RH5_STYLE=1
Otherwise the patch is pointless.
Or hack the patch and remove the "if $RPM_RH5_STYLE; then" conditionals so it's always generated "RH5 style".

There is a CentOS kernel 2.6.24 for testing purposes built by Johnny Hughes. Take a look at this forum thread for details:

Oh, why couldn't it be 2.6.27. Then I would have the patch I need?
But then, reading up on this kernel, my other drivers like dkms probably won't work.....
