How to upgrade CentOs Kernel to latest version?

Hello,

We have a PowerEdge 1950 server running on CentOs 5.3 x86_64 version. On the console, we're keep getting the bellow error on startup.

VS1 login: drivers/usb/input/hid-core.c: couldn't find an input interrupt endpoint.

In several forums they suggested to upgrade to latest version of kernel. Currently we don't want to update/upgrade to CentOs 5.5.

How can I safely upgrade/update current kernel version to latest version? The current CentOs version: CentOS release 5.3 - Kernel 2.6.18-128.1.6.el5xen on an x86_64

Any quick help would be greatly appreciated. Thanks.

Download the kernel and install it using

rpm -ivh kernel-version.......rpm

Once it is finished on reboot you would see Grub giving you options of booting the server in old kernel or to new kernel.

So if by any chance you are unable to boot into new kernel you would also have option to boot into the old kernel and fix any issue you could have.

I'm not sure that you can update the kernel using the traditional update methods for CentOS without it being considered a CentOS revision upgrade, you can certainly upgrade the kernel (it dependencies) without upgrade many of the other applications installed.  However, there will be dependencies that will probably require being upgraded along with the kernel.

I just came to know that, I can run the command "yum update kernel" to update the kernel. I think it will automatically installs the dependencies on installing the kernel.

Try

Notedown the exact version of kernel which your are looking for.For centos5.4 there will be some thing kernel xxx.xxx.xx.i386 or some thing..Not down the exact version of kernel and try

# yum insall the exact kernel version with numbers.i386 or X86

It will install the centos5.4 kernel version.


Thanks
