I get two kernel updates, one for Generic and one for Generic-PAE

I am using Ubuntu 11.10 32 bit on notebook core 2 duo, 4GiB RAM. In order Ubuntu to detect and use more than 3GiB RAM, I apt-get PAE Kernel. The problem comes when there were two update of kernel, linux-generic kernel and linux-generic-pae.

Should I update linux-generic-pae kernel only? if the answer yes, how to stop update notification of linux-generic kernel? I don't want to update the wrong kernel accidentally.

If you don't need the generic kernel, remove it.

If you need it, but just don't want it updated, remove the linux-image-generic package.

To find out which kernel images are installed, run dpkg -l | grep linux-image in a terminal.
