Hi, I am currently running 2.2 on a Chaintech P5 board which has 4 PCI slots available. Two of them are used with two 2940 controllers and the third is used with a 2-channel SMC-Ethernet Card. The dmesg is as follows: ahc0 <Adaptec 2940 Ultra SCSI host adapter> rev 0 int a irq 9 on pci0:9 ahc0: aic7880 Single Channel, SCSI Id=7, 16 SCBs ahc1 <Adaptec 2940 Ultra SCSI host adapter> rev 0 int a irq 10 on pci0:10 ahc1: aic7880 Single Channel, SCSI Id=7, 16 SCBs Probing for devices on PCI bus 1: de0 <Digital 21040 Ethernet> rev 36 int a irq 11 on pci1:4 de0: SMC 8434BT-CH1 21040 [10Mb/s] pass 2.4 de0: address 00:00:c0:ba:73:e0 de0: enabling BNC/AUI port de1 <Digital 21040 Ethernet> rev 36 int a irq 12 on pci1:5 de1: SMC 8434BT-CH2 21040 [10Mb/s] pass 2.4 de1: address 00:00:c0:81:78:e0 de1: enabling BNC/AUI port However, I want to add a third 2940 to the fourth PCI slot. Will there be any problems with the interrupts? Will there be one interrupt assigned two times. Does FreeBSD handle this case properly? Thanks -Andre
