Despite the subject line, that's not an oops, it's a BUG_ON().
And it *should* be fixed by commit ea4039a34c4c ("hugetlb: release
pages in the error path of hugetlb_cow()") although I don't think Andy
ever confirmed that (since it was hard to trigger).
I haven't seen it again, but that probably doesn't mean anything.
I've also fixed a bug in some userspace software I was running, and
that fix means I'm probably not stressing that part of the kernel
anymore. (Even without the fix, it took two weeks to hit this.)
