NixOS 23.11: thermald not working(?)

Help

I recently switched from channel 23.05 to 23.11, and came across this error when rebuilding my system:

warning: the following units failed: thermald.service

warning: error(s) occurred while switching to the new configuration

The only config I have for thermald is:
services.thermald.enable = true;
Removing this obviously fixes the issue, but then I’m not able to use thermald to help regulate laptop temperatures.

And to clarify, my device is a laptop/tablet PC.
I’m running on the latest kernel: 6.6.3. I’ve tried reverting back to 6.5.x, but that didn’t change anything either.

Any thoughts?

Seems to happen on ubuntu too "no temp sysfs"; "stack smashing detected" on 2.5.4 on Ubuntu · Issue #425 · intel/thermal_daemon · GitHub

Seems that this unmerged PR might resolve the problem. If you want to try, you could do something like (not tested):

services.thermald.package = pkgs.thermald.overrideAttrs (old: {
  patches = (old.patches or [] ) ++ [(builtins.fetchurl "https://patch-diff.githubusercontent.com/raw/intel/thermal_daemon/pull/422.patch")];
});

I can confirm that it worked with this patch. This is something that has been bugging me for a while. Thank you for the digging.

Edit:
And now I see it was merged 6 hours ago, so I guess it is just a matter of time before this is fixed without the manual labor…
