I can't know what it is, but all the kernels you list are .38, and all of them are affected by the bug I described, so you haven't discarded anything yet. Try 2.6.39.2 if you want to discard that. All the drivers you've tried are also the same nvidia-drivers, so that's a poor attempt as well. Try vesa, as said. All I say is that user land applications CAN'T hard lock the whole OS unless the kernel let's them do so. And that can only happens because of three reasons: a) kernel bug b) drivers c) hardware Unless it's not truly a hard-lock, in which case the title of the thread is misleading. > I did try .39 but it had issues. I got rid of those. Right, but .38 suffers the bug we are telling you. So you'll have to fix these issues, or you'll never discard the possibility that's the USB bug from .38 bitting you. -- Jesús Guerrero Botella
