mkdir ~/new_kernel && cd ~/new_kernel

# https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6.4/linux-headers-5.6.4-050604_5.6.4-050604.202004131234_all.deb

ls

dpkg -i *

reboot

CentOS 8

#http://elrepo.org/tiki/tiki-index.php
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org -y
yum install https://www.elrepo.org/elrepo-release-8.0-2.el8.elrepo.noarch.rpm

dnf --enablerepo=elrepo-kernel install kernel-ml
# or kernel-lt for LTS version

reboot

Debian 9

非最新内核，但该方法来源官方库。

#https://wiki.debian.org/zh_CN/Backports
echo 'deb http://deb.debian.org/debian stretch-backports main contrib non-free' >> /etc/apt/sources.list
# debian 10 用 buster
apt-get update

apt search linux-image-

另一种方法，内核版本更新一点：

mkdir ~/new_kernel && cd ~/new_kernel

#http://mirrors.edge.kernel.org/debian/pool/main/l/linux/
#linux-image-5.6
wget http://mirrors.edge.kernel.org/debian/pool/main/l/linux/linux-image-5.5.0-rc5-cloud-amd64-unsigned_5.5~rc5-1~exp1_amd64.deb
ls

dpkg -i *

reboot
