Hi all, I'm doing a very informal and unscientific poll: which kernel do you use on your CentOS machines? Not which version of the CentOS kernel, but which repository. Here are some examples I can think of off the top of my head: ==CentOS stock ==build own from CentOS SRPMs ==kernel-ml (from ELRepo) ==kernel-lt (from ELRepo) ==OpenVZ kernel ==build own from kernel.org ==other? One reason I'm curious is that on occasion there are features that I would like to have from a newer kernel (e.g., --want-replacement from md) that (AFAICT) are not in the stock CentOS kernel. I've been using kernel-ml for these but am curious what other folks do in these situations, or whether people default to a different kernel for whatever reason. (And as an aside, who remembers when moving even from, say, a 1.2 to a 1.4 kernel, was an enormous amount of effort? I'm so old. Now anybody can go from a 2.6 to a 3.11 kernel in less than ten minutes!) --keith -- kkeller at wombat.san-francisco.ca.us

I use the stock kernel on this system. * A Thecus N5550 NAS. I use kernel-ml from ELRepo (along with a couple of hardware-specific modules for GPIO & LED setup). I use the "one- shot" LED triggers for drive activity LEDs, and they weren't added until sometime after kernel 3.0. -- =======================================================================Ian Pilcher arequipeno at gmail.com Sometimes there's nothing left to do but crash and burn...or die trying. ========================================================================

I had a laptop which would not boot until I unplugged it and removed the battery. The reason was a faulty mouse driver, and the fix was to remove the mouse driver module prior to shutdown. The problem was that the mouse driver was compiled into the kernel. So I used the SRPM, changed the option to install the mouse driver as a module and recompiled. Following the directions on the Centos wiki was pretty easy. c

Exception is an ASUS laptop that I occasionally use an ELRepo kernel on to test out the various function key support, I have a number of backported drivers from these later kernels to enable the backlit keyboard etc on the stock kernels - with the kabi (?) kernel tracking, once these drivers are created they then work with the stock kernel + patched updates i.e. 6.3 to 6.4.> ==build own from CentOS SRPMs > ==kernel-ml (from ELRepo) > ==kernel-lt (from ELRepo) > ==OpenVZ kernel > ==build own from kernel.org > ==other? > > One reason I'm curious is that on occasion there are features that I > would like to have from a newer kernel (e.g., --want-replacement from > md) that (AFAICT) are not in the stock CentOS kernel.

It's the best of both worlds - I get the stability of the distro kernel with the additional hardware support/functionality I need.

Here are some examples I can think of off the top of > my head:I'm running CentOS-plus on my main workstation but multiple VMs run a custom kernel built from the CentOS SRPMS. I have two systems running CentOS with the upstream vanilla kernel, but these don't get much use.

Here are my very informal and unscientific tallies. This isn't actual systems, of course; it's counting people's responses, so my ~10 vanilla kernels count as one Stock in the tally below. Stock: 16 CentOS Plus: 5 ELRepo -ml: 3 ELRepo unspecified: 2 Custom build: 2 ELRepo -lt: 1 Stock + ELRepo kmods: 1 Oracle: 1 OpenVZ: 1 No big surprise in the results; most people tend to stay with the stock kernel, but quite a few people use one of the others. I imagine that more people who didn't respond would be more likely to be stock kernel users, so the numbers are probably a bit skewed towards the tinkerers and funky hardware or kernel feature requirements. People's reasons for using a non-stock kernel were also not a huge surprise. I don't recall anyone saying that they use a different kernel just to be recent; in the cases I remember everyone had a reasonably specific reason to use a non-stock kernel. That also makes sense here; it stands to reason that CentOS users want stability, and stray from the path only when stability is compromised by sticking with stock. Thanks all for responding! --keith -- kkeller at wombat.san-francisco.ca.us
