Issue/Bug Description:
Kernel was updated to Linux 6.8.0-76060800daily20240311-generic, noticed charge thresholds were not working. The following is from the terminal:

cory@lemurpro:~$ system76-power charge-thresholds
org.freedesktop.DBus.Error.Failed: Not running System76 firmware with charge threshold support

Rebooted with Linux 6.6.10-76060610-generic kernel. The following is from terminal:

cory@lemurpro:~$ system76-power charge-thresholds
Profile: Balanced (balanced)
Start: 86
End: 90

Steps to reproduce (if you know):
Try to change charge-thresholds under kernel Linux 6.8.0-76060800daily20240311-generic, error persists. Can --list-profiles

Expected behavior:
Be able to change charge profiles, especially since I am on a lemp10, running 2023-20-13_5d997d1 firmware. Works fine on the old kernel.

Is system76_acpi loaded?

Forced reinstallation of system76-acpi. It works now.

[ahoneybun]

@phrogpilot73 which command did you use? With dpkg, apt, or something else?

[phrogpilot73]

@ahoneybun I was poking around in Synaptic package manager to see what other versions of the Linux kernel were in there, and thought "YOLO" and then selected the system76-acpi to reinstall.

[jcs224]

I also ran into this. Was also able to fix just by downgrading my kernel to 6.6.10 with kernelstub. Should this be re-opened until this is fixed upstream?

[crawfxrd]

Issue is not in system76-power.

You can fix it by rebuilding DKMS modules.

[ahoneybun]

@crawfxrd that does not always fix the issue, can we move this to system76-acpi-dkms then? It seems to depend on which commands you run when it comes to DKMS if it will fix the issue or not.

[crawfxrd]

Yes it does. Anything that uses led_classdev is broken because of this commit:

• b57f055

This is a breaking change that was made without the kernel version changing, so DKMS rebuilds were not triggered.

[ahoneybun]

I can tell you from the support tickets that it doesn't always fix it. Do you mean this command?:

sudo dkms autoinstall

[crawfxrd]

No. Manually rebuild everything. dkms uninstall followed by dkms install for both the system76_acpi and system76 modules.

[crawfxrd]

#319 shows the actual problem so I will use that issue.

Duplicate of #319.

Neither sudo apt install --reinstall system76-dkms system76-acpi-dkms nor sudo dkms uninstall and then install works on a darp6 for me.
