Those look different, and hopefully should be fixed by commit 1d5bfe1ffb5b ("mm, compaction: prevent infinite loop in compact_zone"). Which admittedly isn't in -rc4 (it went in on Thursday), but I think Dave tends to run git-of-the-day rather than last rc, so he probably already had it.
I *think* that if it was the infinite compaction problem, you'd have the soft-lockup reports showing that. Dave's are in random places. Which is odd.
