It looks really close. There was one sanity test failure basically on
all arches/kernels:

| NOTE: ======================================================================
| NOTE: FAIL: test_stap (stap.StapTest)

| AssertionError: 1 != 0 : cd /lib/modules/`uname -r` && (if [ ! -L build ]; then ln -s /usr/src/kernel build; fi)
| ln: failed to create symbolic link 'build/kernel': File exists

If we can fix that (may need the test to be tweaked?) I'll rerun and
check there isn't anything else. Looks like its hopefully not too hard
to fix!

Cheers,
