 WAPBL disabled (w/o 'log') didn't help during my tests.
 
 But: With that (KVA) hint I played with CUBIETRUCK's config and
 modifying it like (== preserve original std.awin settings and limit
 mem to 1 gb):
 
   #makeoptions   KERNEL_BASE_PHYS="0x80000000"
   #makeoptions   KERNEL_BASE_VIRT="0x80000000"
   options       MEMSIZE=1024
 
 produced a working netbsd-7 cubietruck kernel for me (with the side
 effect that 'bootargs' is no longer found / supported).
 
 Does this help to localize the problem?
 
 Markus.
