This is a fairly serious error, it means someone has manually attempted to remove your kernel and has broken the package management record for the kernel. We do not recommend you ever uninstall a kernel. Linux has a boot loader that allows you to pick which kernel (or even operating system) you want to boot into. If you wish to switch kernels, dont uninstall a kernel or even replace it, just install another kernel and configure your system to log into it.
If your system has been broken in this manner, you will need to try and correct your package management record and to try to reinstall your kernel. The follow is a set of steps that may work, however if someone has manually removed your kernel its likely the system may be in a very abnormal state and these commands many not work. This type of error is not caused by ASL.
Step 1) Attempt to remove the kernel record from the package manager:
rpm -e kernel-PAE
or
yum remove kernel-PAE
Step 2) Attempt to manually reinstall the kernel
yum install kernel-PAE
Note: If your system requires that you do this, your system is in a very adverse state as the package management built into the OS will not allow this condition to occur. It can only occur if someone attempts to manually remove a kernel and does so in a manner that breaks package management. Your system may be in an abnormal condition, and we highly recommend you consider investigating whether other adverse conditions many exist on the system.
