It is stuck then in an endless loop after dcache is disabled before jumping to the OS.

Argh.. That's really bad. May I ask you to debug this a little bit?
What is exact cache function being called? Where from? How comes that dcache_status() returns true after dcache_disable()? Or does somebody call dcache_enable() in between?
