That's got the interrupt controller, and presumably Thomas' tree has the timer. Is it likely to go upstream this dev cycle? Basic j2 board support did, and as I said it hangs before userspace without the rest of the interrupt controller and timer plumbing (which are currently only used by this board). The above message to the j-core list had an attached patch that adds the missing bits to -rc2. I tested that patch and it worked for me: Tested-by: Rob Landley <r...@landley.net> I just checked the current git pull (not quite rc3) and vanilla is still hanging at the same place, and the patch still applies cleanly. I'm aware we're in bugfix-only mode, but "kernel hangs before launching init" seems bug-ish to me. Rob
