But I could have sworn we already did this. Well, we're not going to make the change unless kernel guys want us to. That said, we currently do install the PAE kernel if you have 4 GB+ of RAM[1]. Switching to it by default is problematic because then we're back to using different kernels for different cases and it also makes the 'what do you with the live image' case a lot more complex. The _real_ fix here is to get PAE runtime much like was finally done with SMP :-) Jeremy [1] Well, any memory above 4 GB actually -- so if you have a machine with a large hole and only 3 GB of RAM, you could end up with the PAE kernel _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
