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 :-()
I will fix up the merge on Monday (unless Andrew gets more stuff merged
or updates mmotm for me).
Sorry about that.
