ArchLinux 2012.7.15 UEFI+GPT+LVM+LUKS on an Asus EeePc 1215b
aka "It's-Been-Too-Long-Since-I-Last-Broke-My-Computer Weekend Project"

There's a bug when running 'efibootmgr' to add an entry to the EFI Boot Manager which throws a kernel panic on this computer. Consequently the EFI Shell has to be started manually from the BIOS "Launch EFI Shell from filesystem device".

I'm hoping I can use the EFI Shell 'bcfg' command to add an entry to the efi boot manager, but I haven't figured that out yet.
