It would be great if you could post your kernel module which uses kprobes.

BTW, I am not into ARM, but the error message above AFAIK suggest that
it might hit "un-allocated" memory area. This is just my way to
express a situation where a memory area hasn't been represented by
PTE.

Or in other word, you haven't allocated page(s) for that area but you hit it.

So, any suspects related to the above hypothesis?
