Comment 32 for bug 1652348

Paul Graydon, thanks for the clarification.

Paraphrasing Linus, "We don't break userspace!" So, kernel bits being flipped causing userspace issues would be considered, at least for now, a kernel issue.

Despite this, the Ubuntu kernel commit bisect results are helpful here on Launchpad.

However, in order keep this relevant to upstream, you would want to bisect the mainline kernel as if doing a brand new bisect to see what the results are there.

Once the mainline kernel commit bisect is done, then someone from upstream would give their perspective on is this root caused to kernel, user space, or both.
