Since my report predates bug 68664 by several years, shouldn't bug 68664 be a
duplicate? In addition, my report was much more detailed, since it also
provided a practical use case, showcasing the importance of this problem.

Also if I understand it correctly, you have still not fixed the issue. So
closing it seems to be a bit premature. I'll keep a watch on bug 68664 and will
be sure to reopen my bugreport in the case if the fix does not help on ARM
Cortex A9.

Thanks for generating some sort of activity anyway. It's surely better than
nothing.
