Starting somewhere around v4.0-rc1 and persisting through commit
v4.0-rc7, there is a new NULL deference apparently happening in
conjunction with xfs. This inhibits this machine's booting,
as xfs is used for the root filesystem.
First bisection points at first-bad commit v4.0-rc1~8, and since that is
a merge commit, I'll be investigating some more hand-chosen commits (and
then people to Cc) as we speak.
Boot log of v4.0-rc1~8:
