the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > to compile the Linux kernel needs according to certain steps, including configuration, compilation and installation. If the compilation and linking process is complete, but you can't get into the new system, there are several possible reasons:
Kernel configuration problems: Recompiling the kernel requires modification of the kernel configuration. If something goes wrong during the configuration process, for example, the necessary drivers are not compiled into the kernel or the wrong parameters are set, the new kernel may not start properly.
Module loading problem: After kernel compilation is complete, the new kernel image file and corresponding module file need to be installed into the system. If something goes wrong during installation, such as the new kernel's modules not being loaded correctly, or the installation location is set incorrectly, the new kernel may not start properly.
Boot parameter problem: The kernel needs some parameters to boot. If these parameters are not specified correctly during the boot process, or the parameters are set incorrectly, the new kernel may not boot properly.
In summary, recompiling the Linux kernel requires careful checking of every step, including the kernel configuration, compilation, and installation process, as well as checking the boot parameters to ensure that the new kernel will boot properly. If you still cannot log in to the new system, perform further troubleshooting, such as viewing log files.
