Bug Description

SRU Justification:

Impact: Booting i386 kernels on 64-bit efi firmware does not work on quantal.

Fix: Upstream commit 5189c2a7c7769ee9d037d76c1a7b8550ccf3481c can be cherry-picked into quantal. This commit is already present in raring.

Testcase: Properly boot an i386 quantal kernel on a device that has 64-bit EFI firmware.

--

I have been trying to create a small i386 bootimage for mac using grub efi boot on my new macbook air.
With precise it was not possible to use an i386 kernel on a 64bit efi firmware but this has been resolved with eficross.
But after installing quantal with debootstrap on a usb stick with a small vfat image for holding grub-efi i cannot boot the system with kernel 3.5.18. So I started installing the latest mainline kernel from ppa which worked without problems.

After installing about 10 kernels :) i found that it had to do with the changes between kernel 3.6.4 and 3.6.5, so i investigated the changelog file and there is some significant change for efi cross arch.

    x86: efi: Turn off efi_enabled after setup on mixed fw/kernel

    commit 5189c2a7c7769ee9d037d76c1a7b8550ccf3481c upstream.

    When 32-bit EFI is used with 64-bit kernel (or vice versa), turn off
    efi_enabled once setup is done. Beyond setup, it is normally used to
    determine if runtime services are available and we will have none.

    This will resolve issues stemming from efivars modprobe panicking on a
    32/64-bit setup, as well as some reboot issues on similar setups.

I wanted to take that patch and apply it to the quantal kernel but i get an error while patching so there are more changes for efi (duh).

If someone could help me with this patch maybe this can be added to the quantal kernel?

Regards,

William van de Velde

This bug is awaiting verification that the kernel for Quantal in -proposed solves the problem (3.5.0-20.31). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-quantal' to 'verification-done-quantal'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
