cannot install on kernel 6.9.3-76060903-generic

[bready2die]

running pop os 22, this is what I get.
from what i've looked up, it might have to do with zstd compression, especially since i didn't have an issue when the kernel modules weren't being compressed by default.

Does it work if you build with an older pop-os kernel?

[bready2die]

it works in the 6.8 kernel, but it only compiles after commenting out any CONFIG_* options related to module signing in the kernel version's auto.conf. it seems like module signing got turned on in the kernel at some point, and while verification isn't forced, it will still attempt to sign modules during module_install and throw a fit if there isn't a key. any kind of home-compiled module loading is broken in the 6.9 kernel for me though.
