Hi, all: My machine has one AMD64 3200+ CPU, MSI K8T Neo motherboard, one Realtek 8139 10/100Mbps ethernet card (rl0) connected by 10M ethernet to Internet. Everything works fine but when I compiled kernel with 'options DEVICE_POLLING' and 'options HZ=1000', the kernel boots fine, but fails to bring up rl0 automatically as indicated in '/etc/rc.conf' and fails to assign static IP address to rl0 and fails to add route to default gateway as indicated in '/etc/rc.conf'. According to 'kern.polling.enable=0', device polling is disabled, and I keep it disabled unless I mention otherwise. When I manually configure rl0 using 'ifconfig' and 'route', rl0 doesn't work as I cannot ping other machines (DNS, gateway). More mysterious (and thus an important clue) is even 'ping 127.0.0.1' receives no response. When I 'sysctl kern.polling.enable=1', I see 'kern.polling.suspects' a very very large number (> 750). This indicates sth wrong in the polling implementation. Does anyone has similar experiences? Thanks, Bin Ren
