NetBSD 8.0_BETA macppc powerpc
>Description:
oea_startup() in src/sys/arch/powerpc/oea/oea_machdep.c attempts to "allocate away the pages that map to 0xDEA[CDE]xxxx" as said in the comment by the call to uvm_map() fails. I've tried playing with the size & value fields in the uvm_map call without luck (or clue). 
>How-To-Repeat:
Boot a NetBSD/macppc kernel & dmesg output.
