Hi Len,

I tried your suggestions. Please see comments and data inline below.
This time I'm using stock 2.6.5 for all data with debug enabled.
Hope this helps in further debugging...

Thanks,
Shantanu

That's reassuring ;-)

This works ok though again with only one cpu coming up. Here is the output:
