Specifically, the problem arises when the PXE network card driver is compiled as a kernel module (.ko file). During the installation process, the kernel gets stuck in the 'ip_auto_config' stage, waiting for the network interface to become ready, displaying the message "Waiting up to xx more seconds for network." However, it appears that the system does not proceed to the ramdisk stage to load the .ko driver, ultimately leading to a failed installation. Based on my analysis, it seems that for a successful PXE installation, the corresponding network card driver must be compiled directly into the kernel rather than as a loadable module. I would like to confirm if my understanding is correct. If so, would it be necessary to adjust the relevant code? Because it is not suitable to compile too much ehernet drivers into vmlinux. Best regards, Gang Yan
