I have a router/file server/web server, dual p3 board with two nics one using the tulip and the other using 8139too driver. For as long as I can remember I've had to put noapic on the kernel cmdline to get network to work. Something having to due with local apic and apic being automatically selected when enabling smp. With apic I don't have any network, dhcpcd doesn't work I can assign static ip's and static routes but can't ping anything no trafic in or out. I tried removing the noapic lines all together and it won't even register the network device (ie modprobes just fine but ifconfig -a doesn't show a new network device). And now when I upgraded the kernel to 2.6.16.9 from 16.2 I'm getting the same results as without passing noapic to the kernel. I have no network connectivity with these later releases of the stable kernel. Any suggestions as to why this is happening and what I can do to update my kernel and make things work would be helpful. I've tried passing noapic and nolapic but the kernel apparently doesn't recognize nolapic (documentation fix there). When I remove smp I have the options to remove apic and local apic and things work fine with one processor. However I really don't want to be stuck using one processor on a dual processor system for the rest of it's days. I'm still not getting it to work even with 2.6.16.11 has the same results I already sent this to kernelnewbies but no one responded really so I'm sending it to lkml. - David Brown
