I'd tend to think the same. I've had a quick look at the differences
between the kernels and potential culprit could be at least cgroup or
priority-inheritance futexes. You should probably raise the issue on
the linux-kernel mailing list. Ideally, you should check wether vanilla
2.6.30, 2.6.32 and 2.6.34 kernel also have the issue, and use git bisect
to find out when it stopped working.
