For reference the pinned-manifest.xml lists the kernel at:

<project name="people/andygreen/repo-branch-archive" path="kernel" remote="linaro-other" revision="d2287e4cd2ce9ec10f8dba58b13fbe7004cefff1"/>

The same build works on 4430, log attached.

https://android-build.linaro.org/builds/~linaro-android/staging-panda/#build=41 on 4430 works at:

<project name="people/andygreen/repo-branch-archive" path="kernel" remote="linaro-other" revision="8e46a6a52531ee62d240f2c1093b28b184d35be8"/>

log attached.

Assigned to Andy for review as it may be a 4460 specific kernel issue.

Reproduced it on my shiny new 4460

This should be fixed in

BTW for now the branch archive is in the same place but our main working git tree has moved here

http://git.linaro.org/gitweb?p=landing-teams/working/ti/kernel.git;a=summary
git://git.linaro.org/landing-teams/working/ti/kernel.git

all the other LTs should move shortly as well FYI
