Remote kernel upgrade

If for some/many reasons after a kernel upgrade, the system does not reboot. Some hosting control panels can reboot the server into rescue mode. In this mode, you can edit the lilo.conf to go back to the previous working kernel. Make sure you backup the file first.

Also, if you use “yum update” to upgrade the kernel, the default kernel might have too many extra/redundant modules that might cause the system hang while booting up. If it is the case, use a modified kernel (compile your own) with some minimal modules enabled (can see the modules in /lib/modules/, change the version if needed).
