I located the spot. It's in /sys/contrib/dev/acpi/dsopcode.c:325:
ACPI_DEBUG_PRINT ((ACPI_DB_EXEC, "[%4.4s] OpRegion Init at AML %p[%x]\n",
&Node->Name, ExtraDesc->Extra.AmlStart,
*(UINT32*) ExtraDesc->Extra.AmlStart));
AmlStart is defined as a pointer to UINT8, so it looks like faulty
debug code...
I'll remove ACPI_DEBUG from my kernel config file and try again when
I get a chance.
