setting pte  c1682f6c to eff9c063
just flushed c13db000
boot_ioremap and I return c13db2c0
rsdt = c13db2c0 header is
ACPI: RSDT signature incorrect

the pte we get back from boot_vaddr_to_pte looks to be off be off (or
the data .  Seems odd we set the pte c1682f6c then flush c13db000....  

Still polking around.  I just read Viveks mail he seems to be onto

Thanks,
