Bug#545432: grub-ieee1275: Error loading ext2.mod: symbol `__ashldi3' not found

[Tzy-Jye Daniel Lin]

Package: grub-ieee1275
Version: 1.97~beta2-2
Justification: renders package unusable
Severity: grave

Grub2 is installed to the Apple HFS Bootstrap partition at /dev/hda2.
(It doesn't really fit, but that's a another bug...)
Linux's /boot is ext2 at /dev/hda3.
Linux's / is xfs over LVM at /dev/hda4.

When using the auto-generated
    menuentry "Debian GNU/Linux, Linux 2.6.30-1-powerpc" {
        insmod ext2
        set root=(hd0,3)
        linux   /vmlinux-2.6.30-1-powerpc root=/dev/mapper/vola-root ro  quiet
        initrd  /initrd.img-2.6.30-1-powerpc
    }
this error occurs.

When using the "c" command line, "insmod ext2" results in this error.

If "grub-install --modules=" or grub-mkelfimage/grub-mkrescue is used
to include ext2 in the grub image, this error occurs immediately upon
the start of Grub; the system reboots after the user acknowledges the
error.

In all cases it is impossible to boot the system with Grub2.

It seems as if this libgcc symbol is referenced but not defined in any
of /usr/lib/grub/powerpc-ieee1275/{kernel.img,*.mod}.
