I think these are coming from drivers/acpi/osl.c. Can you stick some
printks in there to confirm this? I'm guessing it's either map_memory or
get_physical_address. (don't forget the { } if adding a second line to a
conditional :)

include/acpi/acoutput.h. Looks for ACPI_DEBUG_DEFAULT (at the bottom)
and add "| ACPI_LV_VERBOSITY1", 2, or 3 depending on how much flood you
want. Recompile.

If it still overflows your dmesg buffer you can either enlarge the dmesg
buffer, or use a serial console to capture the output.
