I give up!
I have battled for several days to get live kernel debugging working on this tablet thing. I first tried a usb debug session, this didnt work. I then bought a usb->ethernet adaptor and enabled network debugging. This also, does not work.
It later occurred to me that all the USB ports are being disabled when enabling any kind of debug bcdedit /debug on basically kills all the ports.
Has anyone investigated kernel debug on one of these devices? Is anyone from Lenovo able to comment on solutions?
