The problem is still in rc4. Reverting the commit still fixes the problem. I tested that warning level messages should appear using lkdtm. While there could be something weird relating to the WARN_ON macro, more likely there is something different about the boots with the kernels I build (the exact way initramfs is built is probably different) and probably that (WARN_ON) code is not getting executed.
