FWIW: I'm also seeing various kernel failures since the changes.

Most my kernel are also using linux.inc from meta-oe which wasn't updated yet
(I plan to look into it soon, unless someone else beats me to it)

The worst part is that some of these issues are random (the race-condition showing
more often than before).

1) do_unpack failing:

ERROR: Error executing a python function in /home/jenkins/workspace/luneos-unstable/webos-ports/meta-smartphone/meta-samsung/recipes-kernel/linux/linux-samsung-tuna_git.bb:

The stack trace of python calls that resulted in this exception/failure was:

2) do_configure failing:
