MPC8347 USB problem : Copying big file[>150MB] discontinuous via Samba

[Sam Song]

Hi all,

We met a USB performance problem on a custom 8347

board with 2.4.31. When copying small files no 
more than 100MB in size, it worked smoothly with 
NEC or VIA PCI card. But copying a big file like 
more than 150MB in size would decrease the
copying
speed a lot. Serial console even couldn't
response 
'ls' command. The target has a 128MB DDR RAM.

While the same driver with 2.4.31 worked fine on
a 
8248 custom board. What could the problem be?

Sorry to distrub you during Christmas Time.

Thanks in advance,

Sam


Best regards,

Sam
