When you said you had this issue with RHEL5 and RHEL6 drivers, have
you

install RHEl5/6 kernel and reproduced it? If so I think I should
install
RHEL6 and try reproduce it locally!

quoted

Yes I reproduced this on both RHEL5 and RHEL6.

So far I tried to scp big file (~1GB) will hit it at once.

Thanks,
Joe

Joe,
Can you please send lspci -vvv output for failing port before issue

occurs.
