The compilation complains it is missing the firmware required by a realtek NIC, probably a setting inherited from the config settings of the old kernel? You eventually compiled it with "N". I suspect the order in which you configured/compiled it plays a role in this error. Since you do not have this hardware, set it to "N", then run: make clean && make && make install modules_install .... <whatever options you normally use here>. Meanwhile, check if you have the firmware file it asks for, which would have been installed as part of 'sys-kernel/linux-firmware': $ ls -la /lib/firmware/rtl_nic/rtl8168g-2.fw -rw-r--r-- 1 root root 4896 May 18 16:15 /lib/firmware/rtl_nic/rtl8168g-2.fw $ qfile /lib/firmware/rtl_nic/rtl8168g-2.fw sys-kernel/linux-firmware: /lib/firmware/rtl_nic/rtl8168g-2.fw When you update world after you have compiled your new kernel, linux-firmware will be installed and the missing file will be available anyway - although no longer needed or used by the kernel.
