You can only resolve it by understanding it.
'Nothing works' is too vague. If you said something like "Accesses to an Avalon-MM slave at address XXX from C code running on a NIOS II processor, causes the processor to lock-up (no communications) ..." that would be a little more specific.
If you have two clocks in the system, then I you must have clock-domain crossing logic in the system to ensure valid data transfers.
Have you tried simulating your design in Modelsim?
