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.
