That seems to be the issue that was causing 6.6.71.

https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.6.71

https://lore.kernel.org/all/3DB3A6D3-0D3A-4682-B4FA-407B2D3263B2@cloudflare.com/

there was not yet any update from xanmod side (first i wanted to hold 6.6.70 due to that).
So we might want to wait for 6.6.71 then.

Do you customize your kernel config? (edit: seems not to, strange that then build for me, i just set v3 compilation, aside that i am on stock too)

[Atemu]

What's odd though is that it builds fine on unstable?

[Shawn8901]

yeah i am running it rn.

╰─ uname -a
Linux pointalpha 6.6.70-xanmod1 #1-NixOS SMP PREEMPT_DYNAMIC Tue Jan  1 00:00:00 UTC 1980 x86_64 GNU/Linux

So possibly its triggered by something by the build environment that is on stable aside the mentioned config settings in https://lore.kernel.org/all/3DB3A6D3-0D3A-4682-B4FA-407B2D3263B2@cloudflare.com/ .
But on that i am honestly unsure. So my suggestion is that we wait for 6.6.71 for backporting and ill create a manual backport for x.70 and x.71 once thats released

[Atemu]

Yeah that's likely. Let's wait for .71 then.
