Everything seems to be ok with latest version

Thank you very much. Regards.

Right, please try the latest kernel. The previous one needed resolve_btfids included in the package for DKMS to build out-of-tree kernels correctly. Latest kernel now includes it.

I built the kernel from AUR and the problem with the display manager is what @vlad1.96 says there's not nvidia.ko.* not in /lib/modules/.

@Anarconda @damentz hid_bpf error and bpf-lsm failed disappear and system is booting (except nvidia), but the nvidia dkms module is not installed.

Error! Bad return status for module build on kernel: 6.6.10-lqx1-3-lqx (x86_64)

Consult /var/lib/dkms/nvidia/545.29.06/build/make.log for more information.

==> WARNING: `dkms install --no-depmod nvidia/545.29.06 -k 6.6.10-lqx1-3-lqx' exited 10

if my localization interferes with reading. I can change it to English and repeat it again

@Anarconda, are you building with the AUR or using the binary package? I'm currently booted into the package built through CI.

Also, you can boot into another kernel and check logs from your previous boot with journalctl -b -1 (add -k for just kernel logs). If you're not using systemd, I'm assuming it'll be in a bunch of files in /var/log.

EDIT: It appears I need to restore a commit: https://aur.archlinux.org/cgit/aur.git/commit/?h=linux-lqx&id=c622099099d1b33802af6cd052ade11d8b527df0

New version is already on the way if you prefer binary build.

@damentz It doesn't boot. Even when system is accessible from another tty the messages stop after show that net is up. No display manager, just stop there.

Can ya'll try the latest release? I made a few changes:

1. Enable some missing DRBG algorithms (hash and counter block mode)
2. Enabled the latent entropy GCC plugin to force more entropy at boot
3. Re-enabled kernel debugging with BTF (required as per https://bugzilla.kernel.org/show_bug.cgi?id=218320)
4. Enabled module compression with ZSTD, switched kernel image to ZSTD compression as well

I can verify the hid_bpf and bpf-lsm errors are gone, but I don't have any systems triggering the jitterentropy error to confirm if my changes helped.

@damentz: I can confirm what @vlad1.96 posts.

and I'm also having this "problem":

With kernel versions 6.6.8, 6.6.9 and 6.6.10 not tests with previous versions.

Thanks in advance.

@damentz Not yet, I'll be looking for a way to find the source of the problem. Now I can only share a part of the code on linux-xen and linux-lqx in common places. There are differences there.

I don't know if it's related yet, but maybe it will lead to some thoughts.

UPD

I checked on an already compiled kernel from liquorix.net (to exclude my configuration changes) and the warning persists

@glorious-yellow: Liquorix uses PDS from Project-C: https://gitlab.com/alfredchen/linux-prjc. However, the maintainer appears to be absent, so I've been maintaining necessary changes and optimizations in Zen Kernel here: https://github.com/zen-kernel/zen-kernel/commits/6.6/prjc

@vlad1.96: That's odd, do you have any kernel output that explains why it fails? The BPF configuration compared with linux-zen is for the most part identical aside from support for kprobe error injection. All the options for BPF as an LSM module and HID_BPF are enabled.
