[20:14] <AKX> Good Day!  Does anyone know what is happening with the Mainline Kernel PPA (https://kernel.ubuntu.com/~kernel-ppa/mainline/)  ...?
[20:15] <AKX> I am suddenly getting an HTTP 404/Not Found error...
[22:09] <JanC> AKX: seems like it's not only the PPA but everything on that domain (like the git repositories)
[22:14] <xnox> AKX: JanC: note that git repositories there have not been used for over a decade already; and they are mirrors from launchpad; and the primary repos we push to are all in launchpad.
[22:14] <xnox> where the ~kernel-ppa home dir went i'm not sure, but will poke people.
[22:14] <xnox> apw: ^^^
[22:16] <JanC> https://wiki.ubuntu.com/Kernel/FAQ still refers there for the git repository
[22:16] <JanC> and probably many other places...   :-/
[22:17] <JanC> it might be useful to put a redirect or some info page in those locations if they are no longer used
[22:20] <JanC> I suppose git is here now: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/
[22:22] <jeremy31> Why not use the Ubuntu mainline kernels?
[22:22] <JanC> if you scroll back a bit their disappearance is what triggered this  :)
[22:25] <jeremy31> I thought mainline was somewhere else, whoops
[22:32] <xnox> JanC: yes, and in addition to that we also now have https://git.launchpad.net/ubuntu-kernel-next which are snapshots of upstream tagged release for each major series; with all ubuntu patches applied and integrated & known to pass build, boot, regression testing. Cause mainline builds do not have many features that are applied in the ubuntu kernels (more hardening, secureboot tightening,
[22:32] <xnox> not-yet mainlined apparmor features, etc)
[23:08] <AKX> Hello Everyone! Well, the Mainline PPA was active until just a week or two ago.  I downloaded and installed 6.1.55 ( 6.1.xyz is a kernel.org LTS Kernel - LTS refers to Kernel.org, NOT Ubuntu ) from debs at the Mainline PPA...
[23:09] <AKX> The upstream Kernel.org LTS kernel is now 6.1.57,,,
[23:11] <AKX> I have been using Mainline 6.1.xyz LTS on Ubuntu JJ 22.04 LTS, and it has been incredibly stable.  The Hardware support has been excellent.
[23:11] <jeremy31> AKX: 22.04 has 6.2 available 
[23:15] <AKX> Yes, but I want to stay on a ( somewhat more modern, but not bleeding-edge ) Kernel.org-listed Long-Term kernel.  6.1.xyz has been designated as the current LTK.  6.2 thru 6.5 are not LTKs.  6.6 may be the next, but I am not sure...  There's still a lot of work going on to support Containers more efficiently and securely.
[23:18] <AKX> I propose that going forward, Canonical should make LTKs (Long-Term Kernels) available via the HWE Repository...
[23:18] <jeremy31> Didn't the 5.15 kernel support your hardware?
[23:21] <AKX> Yes.  But 6.1.xyz with Mesa at this PPA: ( https://ppa.launchpadcontent.net/kisak/kisak-mesa/ubuntu jammy main ) solved **A LOT** of Intel graphics issues.
[23:22] <jeremy31> What Intel graphics?
[23:23] <AKX> I no longer have Page Flashing/Tearing in Firefox, etc.  And this is on an old i5 Gen 4 with legacy Intel HD Graphics, which has already been well-supported for many years.
[23:25] <AKX> It seems there were some regressions in the 5.15.xyz Kernel versions that shipped with 22.04...
[23:26] <AKX> On a lark, I tried the Mainline 6.2, 6.5, and 6.1 series.  After some testing, I settled on Mainline 6.1 Long-Term Kernel.
[23:26] <AKX> Been very happy with it.
[23:27] <AKX> Of course, I need to check manually for new builds of the latest release in that series, but as a whole, I have not really had any issues since I moved to 6.1.
[23:29] <jeremy31> Gen 4 is what. 9 years ago?
[23:32] <AKX> Give-or-take...  I am using a well-refurbished Lenovo T440s, running an i5-4400.  Very clean, all hardware working, little keyboard wear, HDD replaced with 1TB Samsung PRO SSD.
[23:34] <AKX> It's my "daily driver."  Everything works, and works much better on 6.1.x than 5.15.x...  I think the Scheduling in 6.1.x has been optimized quite a bit compared to 5.15.x.  Everything is a lot "snappier" and I am not running into much lag in Firefox, etc. anymore.
[23:36] <AKX> CPU utilization viewing YouTube 1080p30 / 1080p60 hovers around 15% CPU in 6.1.x.  In 5.15.x, it was closer to 40%.
