+Segfault in memory_region_dispatch_write()
+Description of problem:
+Several possible outcomes
+- Kernel freeze and rcu lockup messages.
+- segfault
+ 
+For segfault, using gdb.

+Steps to reproduce:
+1. Boot.
+2. Use gdb to grab back trace after segfault.
+Additional information:
+Seems to segfault mid way through PCI enumeration in the kernel.  Which device seems to vary between runs.
