Comment 2 for bug 1839977

Following by the comment #1 https://bugs.launchpad.net/kernel-sru-workflow/+bug/1839977/comments/1

The cert test shows the test running on rpi2, rpi3 b, and rpi3 b plus are good. It means we skipped the test for rpi3 a plus because of #1841955. I will leave the judgement to others to see if it matters or a real kernel regression.
