But with this patch the "nohlt" has gone. So now we need a solution, that fixes the root of the problem. Hmm at least am3703 boots just fine with v3.10-rc1 except for the deeper idle states not working properly without the patch I posted. And looks like the PM for DT based booting still needs a bit work.
