CentOS7

kernel-3.10.0-693.el7.centos.toa.x86_64.rpm
网盘链接：https://pan.baidu.com/s/1cXB_3qPOnTiIGijFlQ_uzw 将文件上传到服务器。
直接rpm安装会报错，如下：

[root@localhost CentOS 7.2 64]# rpm -ivh kernel-3.10.0-693.el7.centos.toa.x86_64.rpm 
error: Failed dependencies:
	dracut >= 033-502 is needed by kernel-3.10.0-693.el7.centos.toa.x86_64
	linux-firmware >= 20170606-55 is needed by kernel-3.10.0-693.el7.centos.toa.x86_64
	xfsprogs < 4.3.0 conflicts with kernel-3.10.0-693.el7.centos.toa.x86_64
	kmod < 20-9 conflicts with kernel-3.10.0-693.el7.centos.toa.x86_64
	kexec-tools < 2.0.14-3 conflicts with kernel-3.10.0-693.el7.centos.toa.x86_64
[root@localhost CentOS 7.2 64]#

需要先yum安装一些服务,然后再rpm安装。

yum -y install dracut linux-firmware xfsprogs kmod kexec-tools 
rpm -ivh kernel-3.10.0-693.el7.centos.toa.x86_64.rpm

重启后通过uname -r 查看版本，从3.10.0-327.el7.x86_64变成了3.10.0-693.el7.centos.toa.x86_64

执行lsmod | grep toa 检查 toa 模块是否加载，没有加载的话，可通过 modprobe toa命令开启。
正常加载toa模块，回显如下：

[root@localhost ~]# lsmod | grep toa
toa                    12745  0 
[root@localhost ~]#

可以实行开机自动加载toa模块

vim /etc/rc.d/rc.local
modprobe toa

CentOS6

成功过
注：上述命令只在vm虚拟机上测试成功，在hyper-v和物理机上均失败，hyper-v是在编译成功之后，出现网卡丢失的现象，物理机是无法启动centos6.5。

2018年8月29日：经过测试，在hyper-v中，CentOS6.x的系统，均存在编译完内核后，网卡丢失的问题。
