</div>Step 0: Prove to us that your core actually runs reliable and stably at 1Ghz.<br>
<br>
Step 1: Figure out *where* it gets stuck. If you have earlyprintk working on<br>
your board, adding 'initcall_debug ignore_loglevel' to the kernel cmdline often<br>
helps track down where a kernel hangs during boot.<br>
