I can confirm that MIPS does not seem to finish to boot after using the generic idle loop, I have the same problem on a different platform (bcm63xx), and bisecting showed the same commit.

No, after all architectures were converted to use the generic idle loop the config symbol was removed, so it's now always on. The problem is rather that the generic idle loop does not seem to work on MIPS. Unfortunately due to limited knowledge in this area I can't really tell which part broke it. Jonas
