It takes about 5 minutes. The situation is as follows. In module A initialization, a kernel thread is created to update some configuration which is stored in an mtd device. But this thead spent almost 5 minutes to finish writing hundreds of bytes data. What caused this problem? I guess the mtd write was waiting for resources. If so, what kind of resources did it wait for? Thanks. - Shawn.
