System collapse without kernel panic when copy file to a sata-disk or usb-disk
I achieved to run linux-2.6.9 on arm922t development board
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?
