Thanks for trying it out, but it's not really what I was hoping for. I get a bunch of messages similar to these in /var/log/kernel.log, mixed in with a lot of other stuff. AGC:: setMuxRegister:1666 (728, 1, 1) AGC:: setMuxRegister:1666 (710, 1, 4) AGC:: getMuxRegister:1647 (716, 1) = 1 I don't even have message.log. You don't have a kernel.log? Do you see any messages like those if you run dmesg?
