(see patch).

Yes that did the trick when we don't stop/quiesce OF.
 
hmm, you mean if you simply remove 'of_call("quiesce", 0, 0, NULL);' 
from boot_of.c you get further?! 
Are you still closing /chosen/stdout and /chosen/stdin?
I see there is logic there and we only close stdin if (stdin != 
stdout), I wonder if there is a reference count? 
 
My guess and it's only a guess at this point is that OF resets the 
serial port in such a way that our ns driver does not know how to reset.
 
I would agree, because by the time you have scrubbed memory in Xen, OF 
has been destroyed.
One thing you might try is specifying the baud rate in ns16550_init(). 
perhpas SLOF changes it?
