$ git bisect bad 7a55a3d54bd8d9e712e70cf9491f649e7e472a22 is first bad commit commit 7a55a3d54bd8d9e712e70cf9491f649e7e472a22 Author: Bob Moore <robert.moore@xxxxxxxxx> Date: Thu Nov 13 11:08:59 2008 +0800 ACPICA: Add Buffer->String conversion for predefined methods For predefined methods (such as _BIF), add automatic conversion for objects that are required to be a String, but a Buffer was found instead. This can happen when reading string battery data from an operation region, because it used to be difficult to convert the data from buffer to string from within the ASL.
