It seems that it's APIC problem - both fxp0 and em0 are on second PCI bus pci1 and its interrupts are not properly routed: > Dec 2 14:27:28 myhost /kernel: fxp0: <Intel 82551 Pro/100 Ethernet> port 0xbc00- 0xbc3f mem 0xfeaa0000-0xfeabffff,0xfeafe000-0xfeafefff irq 5 at device 7.0 on pci1 > Dec 2 14:27:28 myhost /kernel: em0: <Intel(R) PRO/1000 Network Connection, Versi on - 1.7.16> port 0xb400-0xb43f mem 0xfea80000-0xfea9ffff irq 5 at device 8.0 on pci1 You can try FreeBSD 5.2-RC - it has new APIC code.
