我有以下 syslog-ng 配置
@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); };
但是我的 kern.log 现在只显示以下日志：

使用时sysklogd我曾经获取过所有的信息日志但是切换到后syslog-ng我没有看到这种情况发生？
发生这种情况有什么原因吗？

系统内核详细信息：
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
编辑2：
在 grub 配置中将默认内核日志级别更改为 6，启动后记录表明日志级别已明确设置：
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
但问题仍然存在，我没有看到任何与信息日志级别相对应的内核日志。
令人惊讶的是，日志级别实际上没有设置，
如果我执行cat /proc/sys/kernel/printk，我会看到以下输出，
1 4 1 7
上述输出中第一个整数表示的默认日志级别仍为 1。
