I see a number of runtime failures with this version.
It affects alpha, mips64, ppc64, and x86_64.
Symptom is always the same. There are lots of
BUG: non-zero nr_pmds on freeing mm: X (where X is 1..4)
messages in the log, and the affected VMs don't reboot.
I don't see the problem in curent mainline, nor in mmotm.
Bisect points to "Merge branch 'akpm-current/current'",
which isn't really helpful.
Not sure if this is a bad merge resolution, so just take this
as a heads-up for now.
Yours is the second report overnight (see attached). Almost certainly
a bad merge resolution on my part (its a bit hard when Andrew get part
of his patch set merged by Linus :-()
And now Fengguang's tests caught it as well.
I will fix up the merge on Monday (unless Andrew gets more stuff merged
or updates mmotm for me).
Sorry about that.
No worries. Good news is that test coverage is getting better.
