[Lv Zheng] OK, thanks for the information. However, I feel that there are still improvements we can do here: 1. synchronizing DSDT's DBG operation region to debugcon iobase in acpi-build.c; 2. the readback should be automatically corrected by the isa-debugcon.iobase. What do you think of this? And if one of the above stuffs is useful, do you need me to send a revised patch? Cheers Lv
