Title:
[arm64] nova instances can't boot with 3.13.0-92
To manage notifications about this bug go to:
The most recent d-i for trusty was built w/ 3.13.0-110, so I'll go ahead
and mark fix released. I suspect, however, that this kernel still won't
boot on any modern OpenStack deployment, since the EFI firmware will
require ACPI support that was not available in 3.13.

Hi Tim,
I can't see any arm64 kernel in http://people.canonical.com/~rtg/arm64
-efi-lp1608854/, only amd64.

hopefully not see any arm64 regressions.

This backport patchset is not successful. There are multiple platform
regressions that appear intransigent. Therefore, I've reverted all
patches related to Secure Boot and signed module enforcement. This
should restore arm64 EFI functionality. Platforms wishing to use secure
boot and signed module
Looks good to me :

So, just to be clear, you want us to test

kernel built from git://kernel.ubuntu.com/rtg/ubuntu-trusty.git arm64
-efi-lp1608854 ?

I backported EFI functionality for arm64 and amd64 from Utopic (v3.16)
to Trusty (v3.13) because much of the arch dependent infrastructure in
v3.16 is required in order to support signed module enforcement with a
MOK managed key

I've refreshed the test kernel at http://people.canonical.com/~rtg/arm64
-efi-lp1608854. Please try arm64 which now has a backport from Utopic
(v3.16).

OK. For now I'm using 3.13.0-91 or inferior, which works fine.

Never mind the test kernel. Its bogus according to Dann Frazier. Back to

Now I remember why I thought it was OK to disable EFI in arm64 Trusty.
v3.13 had no arm64 support for EFI to begin with. However, I backported
the UEFI patchset from Utopic (v3.16) which _did_ have arm64 support. I
thought it would be OK to simply disable EFI in Trusty, but clearly
something went
Junien - can you use lts-xenial until I get this sorted out ? The arm64
backport to enable EFI as well as support secure boot signed module
enforcement is going to require quite a bit of effort.
