Thanks Mike for the check.
Given the results even better that we decoupled this from last SRU.
The ppa you tested had all patches that were identified by IBM backported.
@lagarcia:
- do you think there are more than the 5 you identified?
- Given the report that the 2.6.1 from yakkety works there
Just to be sure I installed qemu-system-ppc version 1:2.6.1+dfsg-
0ubuntu5.3 from yakkety-updates and the tests pass.
