Problem with the custom Linux kernel installation.
Problem with the custom Linux kernel installation.
If you suspect something unnecessary is present, wrap it as a module. Then verify whether that module loaded after startup. Opening the configuration interface usually reveals that the "module in use" depends on a sub-option under "driver," which you must activate. The only exceptions occur with certain drivers like vfio, where the relevant option resides in a separate branch of the config tree—such as a disk controller driver in one area and a SATA driver elsewhere (just an example).
When navigating the configuration, focus on standard patterns: look for entries labeled "module will be called [name]" in its documentation or similar symbols. Many settings are automatically enabled or disabled based on defaults. If your system supports file systems and your GPU driver is set to "y," you’re in a better position to understand what’s active.
Disable any "quiet" options in the kernel command line to avoid ambiguity during boot. This lets you see any errors or hangs as the kernel starts. For essential components (excluding proprietary NVIDIA drivers), setting them to "y" simplifies the process, provided you copy the necessary configuration files from modprobe.d/some_module.conf into your kernel and include any required firmware.
Over the past two decades, Gentoo defaults have encouraged manual kernel setup. For a concise reference, consult https://wiki.gentoo.org/wiki/Handbook:AM...figuration. It’s a brief guide that won’t cover every detail but gives a solid overview.
Keep in mind that modern distro kernels often require extensive support for hardware compatibility, so you may need to adapt your approach once you have a working custom kernel.
