Hey John, Don't worry, I know how it is to be busy. For the dmesg/kernel config is it fine if I send you the one from 3.7-rc4 or should I update to a more recent version? I've also now seen this behaviour on another notebook with completely different hardware (Asus VX1). I can send you dmesg output from that one too if you want. Kernel config should be almost identical, but it's running 3.2.29 still.
