Log for Ubuntu 台灣社群
linux (hd0,gpt3)/boot/vmlinuz root=/dev/sda3 initrd (hd0,gpt3)/boot/initd.img boot
路徑什麼的肯定是不同的要自己改，grub 存儲裝置名可以用
ls -l grub 命令查詢root 參數要指定 Linux 根目錄檔案系統的區塊裝置路徑
要用新版核心應該要照著官方的核心源碼編譯流程，要把 NVIDIA 額外的變更套用到新版本的 Linux 作業系統核心源碼去（可能要自行修正 ABI 界面異動造成的相容性問題）
官方的 Bootloader 實現：

那建議是用一個傳統的電腦，插上該硬體後用二元搜尋法(bisect) 找出實際上修正該問題的程式補丁(patch)再想辦法套用到 5.10 版的 NVIDIA 官方核心源碼中
