MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org this was a bug i reported back a few versions as well -- and i don't think i received any responses (nor from the maintainer). i've got a box on which 2.4.x works fine, but 2.6.0-test2 gets into a snit when it's trying to initialize the i8042. i can get 2.6.0-test2 to boot if i add "i8042_nomux". the mux initialization code seems kind of ... wonk -- it seems to write values to the registers then read back and if the value is the same then it assumes the mux is there. that seems way too likely to be broken in situations when the mux isn't there... it'd be better to be looking for some value which is different after writing. the southbridge in this system is the ali1563. if it helps i can supply a complete trace of in/out on ports 0x60 and 0x64. thanks -dean Loading test..........................
