Ok so I think we may have found it... looks like CONFIG_MPIC_BROKEN_REGREAD is what breaks it which is enabled by PA-Semi support in the .config. Can you verify that disabling PA-Semi support removes that option from your .config and that once removed, it works again ? We don't know yet -why- it breaks it, still investigating.
