For some reason, the memset in pcpu_pcpu_populate_chunk() hangs when executing
the rep stos instruction.
The memset is zeroing a chunk of memory starting at fec00000. This might as
well be a virtualbox issue, I can't otherwise explain how the system could hang
in the middle of a single instruction, while still processing timer interrupts.
I have VB 3.1.4, on an x86_64 system, and unfortunately, I was not able to
reproduce the problem here. I am preparing a debug kernel/CD image with lots of
debugging information printed by the percpu allocator to see what is
happenning.
