How you recommend to test kernel? I use Arch and found 3 ways: * Native run, replace existing kernel * Qemu with full Linux distribution, install Ubuntu in qemu and replace kernel in it * Minimal Qemu, need to create initramfs with busybox and connect to Qemu with your kernel, but I even couldn't see printk log from e1000e in this way
Option 3 is the best way since you can't keep rebooting your machine when you reproduce crashes. I did a writeup about it, it might help you. Take a look here: https://bodha.siddh.me/posts/2023/10/14/kernel_qemu_setup/ Thanks, Siddh
