Eu tenho a seguinte configuração do syslog-ng

@version: 4.6
#
# Syslog-ng default configuration file for Gentoo Linux

# https://bugs.gentoo.org/426814
@include "scl.conf"

options {
    threaded(yes);
    chain_hostnames(no);

    # The default action of syslog-ng is to log a STATS line
    # to the file every 10 minutes.  That's pretty ugly after a while.
    # Change it to every 12 hours so you get a nice daily update of
    # how many messages syslog-ng missed (0).
    stats(freq(43200));
    # The default action of syslog-ng is to log a MARK line
    # to the file every 20 minutes.  That's seems high for most
    # people so turn it down to once an hour.  Set it to zero
    # if you don't want the functionality at all.
    mark_freq(3600);
};

source src { system(); internal(); };

destination messages { file("/var/log/messages"); };
destination kern { file("/var/log/kern.log"); };
destination auth { file("/var/log/auth.log"); };
destination mail { file("/var/log/mail.log"); };

filter kern_f { level(debug..emerg) and facility(kern); };
filter auth_f { level(debug..emerg) and facility(auth) and facility(authpriv); };
filter mail_f { level(debug..emerg) and facility(mail); };
filter default_f { level(debug..emerg) and not (facility(mail)) and not (facility(auth)) and not (facility(kern)); };

# By default messages are logged to tty12...
destination console_all { file("/dev/tty12"); };
# ...if you intend to use /dev/console for programs like xconsole
# you can comment out the destination line above that references /dev/tty12
# and uncomment the line below.
#destination console_all { file("/dev/console"); };

log { source(src); filter(default_f); destination(messages); };
log { source(src); filter(auth_f); destination(auth); };
log { source(src); filter(kern_f); destination(kern); };
log { source(src); filter(mail_f); destination(mail); };
log { source(src); destination(console_all); };

Mas meu kern.log exibe apenas os seguintes logs agora:

Jun  7 21:48:03 ash kernel: Loading firmware: rtl_nic/rtl8168h-2.fw

Ao usar, sysklogdeu costumava obter todos os logs de informações, mas depois de mudar para syslog-ng, não vejo isso acontecendo?

Alguma razão para isso estar acontecendo?

EDITAR 1:

Detalhes do kernel do sistema:

Linux ash 6.9.3-gentoo #1 SMP PREEMPT_DYNAMIC Mon Jun 3 21:46:01 IST 2024 x86_64 Intel(R) Core(TM) i5-10300H CPU @ 2.50GHz GenuineIntel GNU/Linux

EDITAR 2:

Alterado o loglevel padrão do kernel para 6 na configuração do grub, logs após a inicialização indicando que o loglevel está explicitamente definido:

dmesg -l info
[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-6.9.3-gentoo root=PARTUUID=4a5f5d65-81be-e24d-bedc-aeb2f0b24295 ro loglevel=6 i8042.nopnp mmio_stale_data=full libata.noacpi=1 resume=PARTUUID=c302ea25-d8e2-064e-8ebd-c79276fad2cc drm.edid_firmware=edid/1920x1080_BOE08E8.bin nvidia-drm.modeset=1

Mas ainda assim o problema persiste, não vejo nenhum log do kernel correspondente ao info loglevel.

Surpreendentemente, o nível de log não está definido,

Se eu fizer um cat /proc/sys/kernel/printk, vejo a seguinte saída,

1       4       1       7

O nível de log padrão indicado pelo primeiro número inteiro na saída acima ainda é 1.
