mtd write takes 5 minutes

[Xiaogeng (Shawn) Jin]

Hi,

I have a weird problem when writing hundreds of bytes to an mtd device. 
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.
