Oops, my bad. vanilla Linux kernel 3.8.4 still has the same problem.
I did not configure the processor type to Exynos (it was VE) when
compiling the kernel.
Linux kernel 3.8.4 still has the same problem and I'm digging into it.

If we see the log below, in this time, translation fault happen at level 2.
I'm just guessing that page table at hypervisor is not properly set.
