Re: Linux kernel unable to boot using EFI
Thanks for the replies, mrunion and WonderWoofy.
@WonderWoofy: I did as you suggested and compiled 3.12.9-1 using ABS, then installed it. I get precisely the same weird results as I do with the 3.12.9-1 kernel release from the Arch package repos.
@mrunion: Thanks again for posting about the USB thumb drive trick. It keeps me from having to revert to an older kernel.
There was a time when I would have tried to hound this down until I got it fixed. I'll just accept this for now, though, and expect for a fix to magically appear in the future. There's still enough non-compliance in the whole UEFI scheme that I'm not too surprised when this kind of thing happens. The USB thumb drive workaround isn't a hassle for me at all. In fact, I'm sort of intrigued by the weirdness of it.

Re: Linux kernel unable to boot using EFI
@dhave,
That is interesting that it didn't work for you. I guess it was worth a try though. I haven't been bit by this bug since something like 3.7 or 3.8, but I established that (for me) it had something to do with the efistub code/functionality. So as a backup solution, I keep grub-efi installed on my machine. Since it loads the kernel in the traditional bootloader way, it doesn't at all rely on the internal efistub functionality.
Honestly, I would rather not have grub on my machine, but it also provides the ability to boot an iso via loopback, so I have it set up with the archiso as well. Hopefully the syslinux project's memdisk functionality will eventually be ported over to UEFI, at which point I will be able to load the archiso like a giganto initramfs. That'll be nice if it ever happens.

@WonderWoofy: Yeah, I keep grub around for similar reasons. It amazes me how long it's taking UEFI to take hold as the norm; maybe it has to do with the large number of non-UEFI-capable machines that Linux is still used on, and the fact that many people go with Linux for the good reason that a lot of distros run fine on older machines.

Re: Linux kernel unable to boot using EFI
FWIW, I'm having success with linux-ck-3.12.9 booting via rEFInd (UEFI, of course). I had to install the latest nvidia-ck (331.38-3) to get to a graphical display, but otherwise, all went fine. After I copied the latest linux-ck kernel and initramfs to my EFI partition, rEFInd found it and presented it to me in the boot menu. All is humming along fine, so far.
