How I run vanilla kernels

cd /usr/src
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.4-rc2.tar.xz
wget https://git.kernel.org/torvalds/t/linux-5.4-rc2.tar.gz
unxz linux-5.4-rc2.tar.xz
tar -xzvf linux-5.4-rc2.tar.gz
tar -xvf linux-5.4-rc2.tar
cd linux-5.4-rc2
make clean && make mrproper
zcat /proc/config.gz > .config
make olddefconfig
make -j9    # maybe j7 id you're already running a VM
make modules_install
#NOTE DEPMOD  5.4-rc2 - VERY IMPORTANT!

cp arch/x86/boot/bzImage /boot/vmlinuz-vanilla-5.4-rc2
cp System.map /boot/System.map-vanilla-5.4-rc2
cp .config /boot/config-vanilla-5.4-rc2
cd /boot
rm System.map
ln -s System.map-vanilla-5.4-rc2 System.map

#/usr/share/mkinitrd/mkinitrd_command_generator.sh

mkinitrd -c -k 5.4.0-rc2 -f ext4 -r /dev/sda2 -m usb-storage:ehci-hcd:ehci-pci:xhci-pci:ohci-pci:xhci-hcd:uhci-hcd:hid:usbhid:i2c-hid:hid_generic:hid-asus:hid-cherry:hid-logitech:hid-logitech-dj:hid-logitech-hidpp:hid-lenovo:hid-microsoft:hid_multitouch:jbd2:mbcache:crc32c-intel:ext4 -u -o /boot/initrd-vanilla.gz

rm config
ln -s config-vanilla-5.4-rc2 config
rm vmlinuz-vanilla
ln -s vmlinuz-vanilla-5.4-rc2 vmlinuz-vanilla
