I upgrade kernel 2.6.25 from testing repository. After that the
computer couldn't see network device. I found that bnx2 couldn't load
firmware at booting time. So I manual load bnx2 module
modprobe -r bnx2
modprobe bnx2
The network device work again. However, the connection delay time still a
problem.
If I change OS to Redhat or Ubuntu, Can solve this problem?
