Since 3.11.y maintenance was discontinued by Greg, Ubuntu took over it. It made me wonder: are we willing to continue 3.11.y for openSUSE 13.1 updates, just relying on Ubuntu? Or, can we just move on 3.12.y?
Fedora 17 Fedora 18 Fedora 19 Fedora 20 Release kernel 3.3.4 3.6.10 3.9.5 3.11.10 Updates latest 3.9.10 3.11.9 3.11.9 -------
Given kernel history for Fedora, I wonder about the apparent conservatism for update kernels for openSUSE. I've never been able to observe a problem using a kernel from Kernel:/stable/standard instead of an official kernel in any openSUSE release. What's the risk in moving up officially?
Despite Linus's hopes, the kernel interface changes over time. Old things get dropped, broken things get fixed with side effects. Plus every kernel comes with its load of regressions. At one time upstream was actually tracking them, see for example: https://bugzilla.kernel.org/show_bug.cgi?id=16055 That's about 150 regression in a single kernel version. The last available list is for kernel 3.7, but the last few lists only had a few bug numbers. I doubt the kernels have suddenly become regression-free, most likely nobody is tracking the regressions any longer, but I suppose the amount of regressions is about the same - one or two hundreds. Thankfully most bugs end up getting fixed. But this means that, if we really intend to switch to a more recent kernel tree, we better wait for the new kernel branch to have matured. So it may make sense to stick to 3.11 as long as Ubuntu maintains it (and we can help them with that) and jump to 3.12 later. Also keep in mind that some other packages depend on the kernel package. For example the nvidia binary driver. You may not like it (I don't...) but people are using it, and it is known that there is lag between every new kernel and its support by Nvidia. AFAIK 13.1 still doesn't have this driver available. Some users are probably waiting for availability before they switch to 13.1. When this happens, if the week after we change the kernel version and that breaks their graphics driver again, they will hate us. So, I am not objecting to changing the kernel version in flight, but I'm saying that great care should be taken if we decide to do it. All dependencies must be carefully taken into account, and the timing must be right too. -- Jean Delvare Suse L3 Support -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
