Hmm. Bisected to Andrew's big chunk of merges on April 1st. Right now I
have
- bad: 527410ff7fc5d45fe41523c0ba061113dea22017 ("cirrusfb: GD5446
fixes")
- good: 63cd885426872254e82dac2d9e13ea4f720c21dc ("ntfs: remove private
wrapper of endian helpers")
and all the commits in between are all from that same -mm series. Very
interesting.
Anyway, the SLUB errors and the per-cpu'ness of the thing seems to have
been a false lead and irrelevant.
Andrew, I'll continue to bisect. Looks like it might be the epoll changes
(that's the only really 'core' thing there). Although I don't understand
why those would make that Mac Mini unhappy, but not affect the other
machines. So maybe I should just stop guessing until the bisection ends..
