Will report back after 1-2 > days. btw, just a tip, it would normally cost half time if the branch is based directly on a mainline (RC) release, eg. v3.13, v3.13-rcX. Because to evaluate a branch, we need to test&compare its BASE and HEAD. If the BASE is v3.* kernels, the test infrastructure will very likely have tested it.
