Now your explanation makes sense.

I have no fast solution for this, but I think that I have an idea how
to fix it. Stay tuned.

Thanks Thomas, wait for your fix. :)

find below a completely untested patch, which should address that issue.

After looking at the thread, I tried to see the issue on OMAP and could
see the same issue as Jason.

Your patch fixes the retries on both CPUs on my dual core machine. So
you use my tested by if you need one.

Thanks for the patch.
And thanks to Jason for spotting the issue.
