Re: Initramfs not loaded or passed to kernel in grub2 UEFI x86_64

[KESHAV P.R.]

Sorry for the late reply. I typed in grub2 (x86_64 uefi) shell
(normal, sh mode) :-


linux (hd0,gpt8)/vmlinuz26 root=/dev/sda7 rootfstype=ext4 ro nomodeset debug=all

[Linux-bzImage, setup=0x3200, size=0x1f9180]

initrd (hd0,gpt8)/kernel26.img

[initrd, addr=0x3fd83000, size=0x27c853]

boot


Again the same "VFS cannot open root device "sda7" " and "append
correct root= option" errors. 1 extra info I forgot to add before,
during kernel panic, CAPS LOCK was blinking but the keyboard and
touchpad were unresponsive. The initramfs is a lzma compressed cpio
archive created using mkinitcpio script of Archlinux.

I guess that the loaded initramfs's memory address and size passed by
grub2 uefi to the Archlinux kernel is wrong. Something wrong in
(grub2-source-dir)/loader/i386/efi/linux.c ? Is there a x86_64 uefi
specific linux.c file or is this the file for grub2 x86_64 uefi initrd
command?

I tried booting Fedora 12 x86_64 kernel and Archlinux's initramfs, it
booted successfully. But dmesg output showed


Trying to unpack rootfs image as initramfs...
rootfs image is not initramfs (junk in compressed archive); looks like an initrd


I am attaching the entire dmesg output. I also tried booting Archlinux
using Fedora's grub-legacy fork whick includes efi and gpt support
(http://git.kernel.org/?p=boot/grub-fedora/grub-fedora.git;a=summary
and http://koji.fedoraproject.org/koji/buildinfo?buildID=161036). Its
grub.efi booted Archlinux successfully. I am attaching its
Archlinux+grub-legacy-efi dmesg output also.
