I need to talk with more people to get more information as it happened
in our test labs. From what I remember, it was caused on 3.10-rt (even
with PREEMPT_RT disabled). We are currently testing 3.10 vanilla, to
make sure that it really does occur on mainline.

I'll keep you posted when we get more data that is relevant to mainline.

This is another reason that the email went out prematurely.
