It goes wrong when I reboot my CentOS7.0 system, after executing yum update -y kernel and selecting the latest kernel version during rebooting.
Executing yum update -y kernel command, the kernel version like below:
current kernel version is 3.10.0-514.el7.x86_64, and the latest version is 3.10.0-693.2.2.el7.x86_64,
After executing reboot command, I select the first kernel (the latest version),
but it goes wrong, wrong details like below:
wn-block(0,0)
CPU: 0 PID: 1 Comm: swapper/0 Not tained 3.10.0-693.2.2.el7.x86_64
Hadware name: ...
Call trace:
...
Kernel Offset: disables
My CentOS version is 7.0, and it was installed basing on VirtualBox.Why does it go wrong?

I have solved the problem, if you want to upgrade your CentOS kernel, you must excute following steps:
excuting
yum install -y kerneloryum update -y kernelcommand;excuting
vi /etc/default/grubcommand, setGRUB_DEFAULT=0, it means that the first kernel will be default kernel;excuting
grub2-mkconfig -o /boot/grub2/grub.cfgcommand(CentOS 7.0 version), it aimes to generate a new kernel configuration;rebootyour system;
Maybe I use this method just in my case, someone who have a good method can add a comment at bellow, thanks.
