bug originally reported <a
href="https://forums.opensuse.org/english/get-technical-help-here/pre-release-beta/483412-12-3-boot-hang-uefi-gpt-system-w-grub2-efi.html";>here</a>
in OpenSuSE forums.

Details on my machine:
Dell Inspiron 15z 5523 with i5 processor, 8 GB RAM, 500 GB SATA main hard
drive (sda), 32 GB mSATA SSD secondary drive (sdb). I have confirmed that I am
using the latest firmware release as of the date of this post.

OS - OpenSuSE 12.3 x64 with GRUB2-EFI bootloader installed

GPT partition layout on both drives:
on /dev/sda
sda1 - 256 MB fat32 EFI-BOOT partition mounted at /boot/efi
sda2 - 256 MB ext4 partition mounted at /boot
sda3 - 8.25 GB swap
sda4 - remainder of disk space as BtrFS partition mounted at /home 

on /dev/sdb
sdb1 - BtrFS mounted at /

When I boot in UEFI mode using the "set page=1" and "set debug=all" flags set
I get a hang at the following output - <a

I am able to boot in legacy boot mode without issue.
