So I'm having yet another problem with my AMD64x2/nforce4 system. Of the two builtin NICs 5.4-S is only recognizing the marvell gigabit chip, which wasn't a problem until I added a 3ware 9500S-12. With the 3ware card in the network doesn't work, take it out and it works. From the dmesg bits below it looks like both twa0 and skc0 are trying to use irq 18 and twa0 is winning. I have the bios set to handle pnp stuff so I don't know whats going on. Any suggestions? --- pcib1: <ACPI PCI-PCI bridge> at device 9.0 on pci0 pci1: <ACPI PCI bus> on pcib1 3ware device driver for 9000 series storage controllers, version: 3.50.00.017 twa0: <3ware 9000 series Storage Controller> port 0xac00-0xacff mem 0xfd000000-0xfd7fffff,0xfcfff000-0xfcfff0ff irq 18 at device 6.0 on pci1 twa0: INFO: (0x15: 0x1300): Controller details:: 12 ports, Firmware FE9X 2.06.00.009, BIOS BE9X 2.03.01.051 pci1: <display, VGA> at device 7.0 (no driver attached) skc0: <Marvell Gigabit Ethernet> port 0xa800-0xa8ff mem 0xfcff8000-0xfcffbfff irq 18 at device 10.0 on pci1 skc0: Marvell Yukon Lite Gigabit Ethernet rev.
