OK now I see. In that case I've been on the wrong track for the last few hours, and explains a lot to me. I had assumed those handlers were AML code, and wanted to know what was getting called. Unfortunately for me, the debug info seems to have meant exactly what it said. :) I understand your theory on what's happening, but wouldn't we have the same problem if acpi_ec_add is being mistakenly called on address_space_handler? Or some other reason the same structure is being assigned for both handlers (like a forgotten increment)? I guess the place to start is to see where/when the "makeshift" ec handler is being installed, where/when the SystemMemory handler is being installed. If they are being installed on top of each other, then it must be some kind of race condition or incrementation problem. Or am I totally insane? -- Pack my box with five dozen liquor jugs.
