Here is the memory map from boot:
real memory = 17179869184 (16384 MB)
Physical memory chunk(s):
0x0000000000010000 - 0x0000000000098fff, 561152 bytes (137 pages)
0x0000000000100000 - 0x00000000001fffff, 1048576 bytes (256 pages)
0x0000000001b32000 - 0x000000000fffffff, 239919104 bytes (58574 pages)
0x000000001000b000 - 0x00000000a069dfff, 2422812672 bytes (591507 pages)
0x0000000100000000 - 0x0000000432df2fff, 13738389504 bytes (3354099 pages)
avail memory = 16297324544 (15542 MB)
I reverted everything to r279220 and rebuilt world/kernel, doesn't make any
I'm gonna try to make some more debugs tonight, in case you want me test
anything else, let me know.
