System collapse without kernel panic when copy file to a sata-disk or usb-disk
 

Hi

I achieved to run linux-2.6.9 on arm922t development board

with busybox-1.11.2.

Now i want to mount a sata disk (250G) to the board,i insert the

related modules,and mount the disk to board successfully,

i copy 1M file from nfs-server to the disk,it is all ok.

When i try to copy a more large file to the disk (10M above) ,

system collapse without any hint or kernel panic information ,

the cursor just stay there with no response even

i knock on the kerboard.

then i try to do the same to a usb-disk,the problem aslo exist.

How can i resolve this problem or how can i locate where the problem

occure,any hint for me?

thank you
