Hi Zhiyi,
I'm guessing here, do you have a 3COM ethernet driver on this machine?
If so, try removing these lines
CONFIG_NET_VENDOR_3COM=y
CONFIG_VORTEX=y
from l4linux_config_ia32[_vga|_fb]*
and/or commenting out the lines that initialise networking in the root
filesystem's /etc/init.d/rcS


Please find attached a patch that does this. Obviously I haven't tested
this.

Kind regards,
Hal Ashburner
