| I'm not sure if I'm allowed to say this here (I apologize to the admins if I am in the wrong). I'd suggest you post this certain problem in the CentOS forums. This problem has probably already been addressed there.

| You probably did not install your kernel correctly.
what is exactly the error you get on screen when booting the new kernel?
Usaly if there is some sort of kernel bug in your current running official dist kernel then they will supply a update for it as soon as possible.

First I install the kernel following these steps :
downloading the latest kernel 2.9.25.3 from kernel.org in /usr/src/ directoryextract the tarball and go to the created dircoping the old configuration to the current dir ( new kernel dir )exucting : make clean && make prepareexucting : make menuconfigloading the oldconfigurationsetting a name for version ( -wahb )save and exitrun make rpmrun rpm -ivh /path/to/kernel.rpmedit menu configreboot server shutdown -r nowany problems ?
I can`t see any thing I dont have remote connection to the server
thanks

| You dont need to compile the latest Vanilla kernel from kernel.org for "Security Reasons". Just make sure you are using the latest Kernel provided by CentOS with a simple "yum -y update kernel".
You don't really need to compile your own Vanilla kernels unless you want to add in additional patches or drivers.

| Looks about right. But compiling a kernel is not as easy at it looks like. You should check carefully what extra options you need or do not need. Maybe some changes were made to the kernel that does not support your hardware and so on and so on.
Try to ask a remote hands request to boot the old (working kernel). And maybe ask a third support party to recompile your kernel.? Thats why I recommended testing a kernel compile first on a test server before you really do it on your live server.
