fsync/futex patches are already added. Would be cool to be able to test futex2 (in unstable) because using custom kernels on Manjaro is a big hustle for me without Nvidia dkms and all that. I already built and installed the 5.10 source with the patch and it boots fine but nvidia is there to kill the day.
Why do you think that there wouldn’t be any nvidia-dkms issues in a kernel provided by Manjaro?
Well, if you are using the same PKGBUILD as the Manjaro 5.10 kernel (except adding your desired patch), then half of your battle is over.
Keep plugging on…see if you can come up for a solution for your driver issue(s).
