Boot freezes at memset_io in early_init

Hi all,

When booting the kernel, it freezes at this line in arch/ppc/setup.c:early_init
317        memset_io(PTRRELOC(&__bss-start), 0, _end - __bss_start);

I searched the list's archive and found this post [1] which has a
similar problem than I, but there isn't any solution posted.

What could be causing this?
I'm using the PPC405 in a Xilinux XUPV2P board with a Virtex II FPGA.

Thanks,
