[U-Boot-Users] Can't call printf() in functions called via function pointers?

On and 8323E-MDS, I added a printf() to fdt_set_qe_busfreq():
static int fdt_set_qe_busfreq(void *blob, int nodeoffset, const char *name, bd_t
*bd)
{
u32 tmp;
/* Create or update the property */
printf("%s:%u\n", __FUNCTION__, __LINE__);
tmp = cpu_to_be32(gd->qe_clk);
return fdt_setprop(blob, nodeoffset, name, &tmp, sizeof(tmp));
}
Adding this printf() causes the system to reset. The odd thing is that I can
add all the printfs I want to ft_cpu_setup().
Is this because fdt_set_qe_busfreq() is being called via function pointer, and
these calls are screwed up because of the relocation?
