Didn't make a difference AFTER you patched the AML or before? Be sure not to load your custom DSDT while testing reverting that file. If you tested this way, then your result is correct. Basically, your ASL is buggy but I hope to have workarounds in our local interpreter to avoid patching ASL if at all possible. > My dmesg: http://people.freebsd.org/~mtm/mobile.dmesg.v > Original acpi ASL: http://people.freebsd.org/~mtm/mobile.asl > Patched acpi ASL: http://people.freebsd.org/~mtm/mobile.asl.patched All of these are 404. -Nate
