The problem here seems to be the line: "BUG: kernel test crashed"
Can someone give me some clarity on what that refers to?

My experience in the last week indicates I can't trust the commit the
test bot tells me is the problem commit on these tests. So if there is
an issue I need something more to track it down with than a line of
output I don't have the source to.
