我正在尝试为 void linux 构建 4.13.2 内核来获取 Vega 驱动程序，但无法启动它。
构建过程：
cp /boot/config-4.12 .config
yes "" | make oldconfig
make nconfig
Changed processor type
Include ext4 by default
Made sure AMD drivers are included
make -j32 bzImage modules
make modules_install
System.map /boot/System.map-4.13.2
arch/x86/boot/bzImage /boot/vmlinuz-4.13.2
.config /boot/config-4.13.2
dracut -f /boot/initramfs-4.13.2.img 4.13.2
update-grub
我尝试根据现有配置进行配置，该配置可以正常启动。
一段时间后，它会进入 dracut 调试 shell。 dmesg 充满“正在扫描所有 btrfs 设备”，直到出现“无法启动”消息。既不存在/dev/nvme*也不/dev/disk/by-uuid存在。
文件系统表：
/dev/nvme0n1p1 swap swap sw 0 0
/dev/nvme0n1p2 / ext4 defaults 0 1
/dev/nvme0n1p3 /home ext4 defaults 0 2
tmpfs /tmp tmpfs defaults,nosuid,nodev 0 0
我在创建 initramfs 时确实遇到了一些错误，但我不明白它们之间的关系：

我不确定下一步是什么？
答案1
我通过跳过 initramfs 并将所需的内核模块包含到内核中来使其工作。
我lspci -kk | grep "Kernel modules" | sort | uniq可以列出当前正在使用的模块以及它们和默认配置，我可以启动并运行它。
