Hello, I've recently completed an LFS build using GRUB-2.03~beta, and

doesn't
even panic, it just sits.
Here are some configuration files

Remove the quiet parameter from the above entry. By doing so, you
might get more details on what is failing.
I'm asumming you are seeing the grub menu, and the blank screen you're
getting is after grub tries to launch the linux kernel.

Wayne.
Unfortunately this does not change the behavior :(. I believe I added
this on later in testing just to see what would happen, if anything.
Thanks, Jacob.
Mount tree in Arch linux host:
sdc 8:32 0 931.5G 0 disk
├─sdc2 8:34 0 931.3G 0 part /mnt/lfs
└─sdc1 8:33 0 260M 0 part /mnt/lfs/boot/efi
UUID's:
lrwxrwxrwx 1 root root 10 Oct 29 14:42 04ED-C3D3 -> ../../sdc1
lrwxrwxrwx 1 root root 10 Oct 29 14:42
d6788259-f948-4164-ae29-d1b996ffd6d9 -> ../../sdc2
I've corrected the root from what it would be on Arch Host (hd2,gpt2
being mounted as /dev/sdc) to when I investigate on grub command line
(hd0,gpt2), so it is finding the kernel. I've attempted to switch out
UUID's for /dev/sdX, however this still fails. Grub2 efi-directory
was
set to /boot/efi on installation. All the correct kernel options were
set during compilation for UEFI installations.
