Hi Martin, I will circle back with KY and reply by tomorrow morning on
this. What we are trying to convey here is that this was discussed with
the kernel folks and they shot down the kernel patch which would have
got rid of the udev rule.

> Please include the memory hotadd patch 
I apologize for not being clear In the above statement. I meant to imply that please include the udev rule we have provided as without it we will run in to kernel panics.

If you absolutely do not want to include the udev rule we can send you
the kernel patch which was debated upon and perhaps you guys can carry
that until further resolution with the kernel community.

Let me know what you think.
Thanks,
Abhishek
