Hi,

that brings us much closer to the solution for your problem. It doesn't
seem to have anything to do with the mentioned __wake_up function,
however. This means that there is no matching entry in the proc_info
table. What is the processor id of your cpu? Probably you have to add a
new entry for your cpu in arch/armnommu/mm/proc-arm6,7.S.
