Looks like it could be an unbalanced of_node_put causing a node's
refcount to underflow, probably the root node.  The warning in
kref_get has unearthed a couple of these recently, see

http://patchwork.ozlabs.org/linuxppc/patch?id=8840

for example.

Joakim,

In your board code do you having something like:

         np = of_find_node_by_type(NULL, "qeic");
         if (!np)
                 return;

         qe_ic_init(np, 0);
         of_node_put(np);

in _init_IRQ?

if so remove the of_node_put() after qe_ic_init() and see if the  
issue still exists.

Joakim,

         if (!np)
                 return;

         qe_ic_init(np, 0);
         of_node_put(np);

in _init_IRQ?

if so remove the of_node_put() after qe_ic_init() and see if the
issue still exists.

If this ends up being the issue we'll change qe_ic_init to stop doing  
the of_node_put() and change ipic_init() as well.  But lets first  
validate that this is the cause.
