I'm having similar problems, but on Intel hardware. See:
http://forum.m0n0.ch/index.php/topic,5124.0.htmlI can always get fully booted, but it's only a matter of seconds to minutes before it crashes with nothing in the logs or console to provide a clue as to what's happening.
It could be tough to get to the bottom of this without anything being reported by the system. Sorry to hear you are having problems, but I'm glad that I am not alone
1.33 runs flawlessly on the same hardware.
