It's posted now at:

Care to try it?

Setting CONFIG_EARLY_PRINTK=n doesn't fix the problem I'm seeing.

I also tried building a v3.8-rc6 kernel with the old v3.7-rc config that 
was used before; no luck.

Let's try to identify and get rid of bootloader dependencies in the 
kernel.  They indicate that the kernel isn't initializing something 
appropriately, which could cause strange problems later.
