Linaro 2.6.37 git tree not booting?

Hey Nicolas, Over the last few days I've been playing with recent kernels on a BeagleBoard xM. So far I've gotten Linus' v2.6.37 kernel booting, as well as the android-2.6.37 git tree booting as well. However, when I try to boot the latest linaro 2.6.37 git tree, I just get:

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

And nothing else. I've tried enabling early printk, but still nothing.

I'm working on bisecting down what broke since 2.6.37, but if you have any hints, I'd appreciate it!

thanks -john
