Grub hangs when trying to boot a kernel. Affects both the -ARCH kernel and a custom -zen kernel.

No visible error messages. Unblinking cursor in the upper-left corner. Ctrl+Alt+Del reboots.

Problem vanishes after rebuilding grub with an old GCC. To clarify, Grub has been built with these packages installed:

Thinkpad X220t, firmware 1.37
grub-2.00-1, x86_64-efi
linux 3.9.7-1
This task depends upon

I was bitten by this issue on my AMD E-350 based system.

@heftig Your build rescued my system. I was unable to get recent grub packages from A.R.M. Thank you!

@tpowa Does your build include changes that relate to this issue specifically? I would try it but I can't afford system downtime until this weekend.

heftig confirmed working grub package, it's the latest branch with tons of patches included.
Fedora is at the moment of 500 patches to latest avaiable source code.
Quite difficult to cherry pick the commit which makes it work again.
