Hello John, sorry for the delay. I was able to do some more testing. At first it seemed that things were working with gcc 4.8.1 (arch upgraded). However when I switched to Linux 3.9.5 I hit the same problems again. The config options are different. Some configs that worked with 3.9.4 broke, some that did not work boot now. I have seen boot failure with kernels compiled using gcc 4.6 as well. I will have to check which configuration that was. Since the arch package is unpatched I suspect, this is not an arch issue: https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/gcc I find it quite strange that I was unable to find reports of problems similar to mine on the web. Perhaps it is a firmware issue?! I have don't know much about the UEFI boot process. Perhaps the firmware expects some address to be alignment in a certain way?
