Bug#648766: Another LOCKUP this time on CPU1

[Kieron Gillespie <ciaran.gillespie@gmail.com>]

So I have obtain a similar error again, this time CPU1 locked up though.

Once again all I have are images of the crash, I am still trying to set 
up a serial connection so I can log these errors better. I am right now 
trying out different configuration options in the kernel to see if one 
of them can fix it, including disabling SMP. I hope that this isn't the 
case as it would be a waste to have a whole CPU sitting around. I have 
also noticed that the error only really seems to occur if Xorg is 
running. I was wondering if the original bug occurred while Xorg was 
running as well?

I will copy the trace as soon as I have time to do it by hand.
