tp_smapi reported as missing/not installed in LTS 24.04 (kernel 6.8.0)

[nap-commit-nap]

X220 here. I used to be able to report battery cycles with tlp-stat -b until I started using 6.x kernel. Now tlp reports that tp_smapi is not loaded despite newest tp-smapi-dkms being installed (0.44 from the package maintainers). lsmod does not indicate tp_smapi.
I had this problem before in 22.04, but it could be solved by downgrading kernel back to 5.x -- unfortunately this is no longer possible with 24.04. I guess something is preventing this module from loading. Help?

How are you loading the module?

[nap-commit-nap]

I'm assuming it's always auto-loaded on boot (defaults). In the past, I'd install tp-smapi-dkms and (maybe) reboot, this would typically report the module as installed (and loaded)?

The module is not automatically loaded.

You gotta add it to /etc/modules or whatever your OS is using

I finally found information on the official tlp website that as of 23.10 and 24.04 the package from the official Ubuntu repository is broken and will not build and install tp_smapi. More info here: https://linrunner.de/tlp/installation/ubuntu.html -- thanks for your replies!

But the package in 23.10 and 24.04 is (almost) identical to the one in Debian 🤔

Does it work with Debian's package?

[nap-commit-nap]

It works with the Debian package. I had to install it using a different package manager because apt insisted on installing from Ubuntu repositories. I loaded the kernel module manually, launched tlp-stat -b and the additional attributes were reported (cycle count etc).
