Missing module BTF, cannot register kfuncs

Snapshot Openwrt gl-inet mt-2500.
I installed snapshot from firmware-selector and now I see such errors in the log. Although the router itself seems to work fine, wan pppoe also works, vpn (singbox) works for certain domains, the local network also works fine. But can someone help and tell me what these errors mean and how to fix them in the openwrt log:

Whatever inplace automated debugger you installed it asks for debuginfo i.e even bigger kernel.

One of these: adguardhome autocore automount base-files bind-dig busybox ca-bundle cfdisk coreutils coreutils-timeout curl dnsmasq dropbear e2fsprogs f2fsck fdisk firewall4 fstools gawk iperf3 iptables-nft ipv6helper kmod-crypto-hw-safexcel kmod-gpio-button-hotplug kmod-leds-gpio kmod-mt7915e kmod-mt7981-firmware kmod-nft-fullcone kmod-nft-offload kmod-phy-aquantia kmod-phy-realtek kmod-usb3 libc libgcc libuci-lua libustream-openssl logd lsof luaposix luci luci-i18n-attendedsysupgrade-ru luci-i18n-base-ru luci-i18n-commands-ru luci-i18n-firewall-ru luci-i18n-opkg-ru luci-i18n-sqm-ru luci-lua-runtime luci-theme-bootstrap mkf2fs mtd nano netifd nftables odhcp6c odhcpd-ipv6only openssh-sftp-server opkg partx-utils ppp ppp-mod-pppoe procd procd-seccomp procd-ujail uboot-envtools uci uclient-fetch urandom-seed urngd zoneinfo-europe

perhaps autocore ?

Please post output of

Perhaps YOUR fork distribution, just install OpenWRT to resolve YOUR problem.

My question is, do these messages talk about a problem that needs to be solved or i can ignore it, that is, about what are these messages?

Messages are about you need to ask immortalwrt, because they include packages not present in OpenWRT and can help you with kernel debuginfo to support those packages.

The link from immortalwrt leads here to this forum. They probably don't have a separate forum. Well, that's fine. Close the subject.

To be told them here:
