I have a Intel Seattle (SE440BX) mainboard running 3.4-S with the following bootup messages: Apr 21 22:20:37 io /kernel: fxp0: <Intel EtherExpress Pro 10/100B Ethernet> rev 0x08 int a irq 11 on pci0.13.0 Apr 21 22:20:37 io /kernel: fxp0: Ethernet address 00:90:27:ad:44:4a Apr 21 22:20:37 io /kernel: fxp1: <Intel EtherExpress Pro 10/100B Ethernet> rev 0x08 int a irq 11 on pci0.14.0 Apr 21 22:20:37 io /kernel: fxp1: Ethernet address 00:90:27:ad:44:c6 Apr 21 22:20:37 io /kernel: Probing for devices on PCI bus 1: Apr 21 22:20:37 io /kernel: vga0: <Matrox model 051f graphics accelerator> rev 0x00 int a irq 11 on pci1.0.0 Having just built another PC I learned that it's not optimal to have pci devices sharing IRQ's. So, not knowing about how FreeBSD interfaces with the hardware, I'm wondering if I'm sacrificing performance by having 3 devices using IRQ 11. Should I move cards/reconfig the BIOS to use unassigned IRQ's?
