The DSDT code clearly can't touch the hardware itself - hardware access is carried out by the kernel. If we can identify cases where ACPI reads and writes would touch resources claimed by other drivers, that would be a good starting point for working out what's going on. Of course, this ignores the case where the DSDT just traps into SMM code. That one is clearly unsolvable. -- Matthew Garrett | mjg59 at srcf.ucam.org
