[arch-general] need to run previous kernel

With grub what should be done when grub boots to run the kernel used before the current default kernel? On the older amd machine I have I tried installing linux-amd and the git site timed out on me twice. I think that was during that last ddos attack though. The newer machine has linux-amd installed and running on it. The current kernel on the older machine that got updated yesterday has a serious speech impediment. This speech impediment effects espeakup and if I can I'm going to find out if it also effects fenrir. --
