Comment 18 for bug 1954676

Oh, my bad - I remember checking that I had the right compiler version, and even verifying that the patch is in by compiling some samples, but I guess then I ran a full upgrade after adding -proposed.

Unfortunately, downgrading the toolchain did not help - both manually built and dkms-built modules still load just fine for me.
