HI

I would like everyone's opinion on this.

I'm trying figure out the benefits of either staying with the LTS kernel or with the lastest kernel. The machines are every day use and stability is important.

Am I tossing away any benefits, of the latest kernel, if I use the 4.8x/9x kernel. Or do the benefits of the 5.1x kernel out weigh any instability?

I'd like all schools of thought.

Just my 2¢: If you are not running into any issue with the old/stable kernel, why change? Is somthing in 5.XX, that you miss now? You might get bitten by something like the thinkpad_acpi-spaming-dmesg-issue as happened to me. Is the 5.XX packaged with your distribution? If not, then I would not do it (well, I maybe would on my testmachine, but not on something that's not in my instant reach).

Nik

Thanks in advance,

Kate

Kate,

Unless you have super-new bleeding-edge hardware that needs a new feature added in 5.1 that is not available in previous versions -- then 5.1 provides absolutely no benefit. Any tweak that 5.1 provided to help with Spectre performance mitigation, etc.. will likely be backported and in a LTS kernel.

I have Arch (that always runs the current upstream version of the kernel, 5.1.9 currently), and Arch also provides an LTS kernel using 4.19. I have a SuSE leap 42.3 install running the 4.4 kernel, SuSE leap 15.0/15.1 installs with the 4.12 version, I have a Pi running Debian/jessie with the 4.9 ARM kernel, and from a general computing/feature/functionality standpoint, it makes no difference.

Now if you have bleeding-edge hardware that is only supported in the latest greatest kernel -- then yes, there is a difference, otherwise you won't know the difference.
