Subject: Re: [3.9-rc1 x86] Bug in ioremap code?

Could you also add the following to your .config:

	CONFIG_ACPI_DEBUG=y

and boot with these on the kernel command-line:

	acpi.debug_layer=0xffffffff acpi.debug_level=0x2

I _think_ that'll shed some light on exactly which ACPI table is being
parsed when the BUG_ON() trips.  That will hopefully let other folks
reproduce it more easily.
