Ah, CONFIG_CPU_IS_SLOW is not set on the machines we tested.

No, unfortunately. I'm amazed no one has tried this out, as it is very
easy to show. I thought people would have been more worried about time
being broken for 2.2.0

That's okay, thanks for the replies, at least I know someone is
listening.
I have looked through the 2.1.126 patch, but I still can't see what
would break it like this. There are quite a few changes, but they do
seem to be interrupt masked anyway. This happens so often, you would
think it would have to be some code that runs fairly often.
I hope you don't mind me sending this to the list, I'm hoping somone
will read it if I keep the thread live.
Stephen.
