..post a one core snip of your /proc/cpuinfo, I'm wondering
if you've hit some 36 bit address space ceiling. I have ...
root@celsius:~# cat /proc/cpuinfo
processor : 1
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz
...
bogomips : 3989.93
clflush size : 64
cache_alignment : 64
address sizes : 36 bits physical, 48 bits virtual
power management:
...and:
root@celsius:~# qalc 2^36bytes to GiBytes
(2^36) * byte = 64 gibibytes
