Are the kernels at http://download.opensuse.org/repositories/Kernel:/stable/standard/ suitable for use in Leap 15.4? Background: It seems that ASUS removed all WMI support from its motherboards with the X570/B550/TRX40 chipset (apparently as a result of AMD doing so so for the X670/B650 chips (?) ), and that broke temperature/fan speed monitoring on those boards. The lack of WMI support means the NCT6775 module is loaded on these systems, but previously, that driver attempted to read/write directly to the ACPI table, which according to this discussion: https://bugzilla.kernel.org/show_bug.cgi?id=204807# (see especially comment 37) is rather bad thing to allow. The patch to NCT6775 was only accepted into the kernel beginning with ver 6.1.2, and has not yet been backported to the 5.14 kernel. Therefore, to regain temp/fan speed monitoring, I need to install that kernel or later (ver 6.1.7 was just released on download.o.o today).

Can you open a bugreport at bugzilla.opensuse.org often they can backport hardware enablement changes for SUSE / openSUSE kernels even if they aren't backported to a mainline kernel. -- Simon Lees (Simotek) http://simotek.net Emergency Update Team keybase.io/simotek SUSE Linux Adelaide Australia, UTC+10:30 GPG Fingerprint: 5B87 DB9D 88DC F606 E489 CEC5 0922 C246 02F0 014B

I can open a bug report if you think it would do some good, but do you think they would do a backport, given that the 6.1.6 kernel was just added to Tumbleweed yesterday, and the 15.5 GM release less than 5 months away?

Without knowing whether 15.5 will have a 5.14 or newer kernel at release, can you expect it to show up in 15.5 if nobody does file a report, or nobody reports soon enough?

Good point. I was assuming 15.5 would have the 6.1.x kernel since Tumbleweed now has it. There's another, but minor, issue with the asus_ec_sensor module; I'll file both reports as soon as I've got them both fully clear in my mind. (A programmer I most certainly am not.)

Not an astute assumption. 15.4 was released with "5.14" when TW was using 5.17. 15.3 was released with "5.3" when TW was using 5.12. 15.2 was released with "5.3" when TW was using 5.6. Leap kernel version numbers are poorly indicative of what really comprises them. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg.

15.4 was released with "5.14" when TW was using 5.17.

I never pay attention to this sort of detail, so it certainly was a reasonable assumption then -- and, IMO, still is: There is a huge distinction between a difference of a few minor versions, and a difference in the major version. Which brings us back to my original question: can the kernels in that repository be used with Leap 15.4?

Linux kernel does not have a major version. All versions are equal.

The kernel itself - yes. But kernel RPM likely has some binaries which are built against Tumbleweed libraries so their requirements may be missing in Leap. What stops you from simply trying to install RPM and boot the kernel? It takes much less time than these back and forth messages.

Probably more importantly - kernel RPM built against Tumbleweed will be using newer versions of infrastructure (RPM macros, tools to install/remove kernel etc) which may be no more compatible with Leap.

Perhaps because before doing that, I would like to know if anyone using that repository has faced any issues?

...

It would help if people would simply answer the damn question if they can, otherwise just stay out of the way.

The content of those requirements differ. You won't find kernels in /boot/ on TW any more, only symlinks to vmlinuz files in /usr/lib/modules/<ver>/, while Leap's modules still live in /lib/. Do you think Leap's old versions of perl-bootloader and/or yast2-bootloader could handle that?

You are welcome Darryl, I have an ASUS ROG STRIX G17 and I had to move to kernel 6.1.x, for a full laptop experience. On Thu, Jan 19, 2023 at 2:26 PM Darryl Gregorash wrote:

Based on the note at https://build.opensuse.org/project/show/Kernel:stable, nope. "Note: this kernel requires Tumbleweed glibc. To install on Leap use the Kernel:stable:Backport project." So, https://build.opensuse.org/package/show/Kernel:stable:Backport/kernel-defaul..., I'd guess (6.1.7 atm). Pedja

Yes, it's kernel:stable:backports: i+ | kernel-default | Paket | 6.1.7-lp153.2.1.g872045c | x86_64 | Kernel-stable-backport on Leap 15.4 also Leap 15.5 I think.

No problem, but, as someone in the thread already said, you might want to think about opening a bug report about this, since, AFAICT, 15.5 will also ship with 5.14.21 kernel, based on what's currently in sle15sp5 kernel repo and the fact that SP5 is supposed to be a 'conservative' release. Pedja
