I ran into the same issue on the XPedite5370 which also uses the 8572.
I worked around it initially by disabling CONFIG_MP.  I was recently
working on an 86xx board and it has the same issue as well when
CONFIG_NUM_CPUS > 1.

We try and use the same memory layout (which unfortunately has flash at
the top of memory) on all our boards so I'll send a patch to fix this
issue at some point unless someone beats me too it:)

Best,
