That's supposed to be the case and is usually the case. However, when left to its own devices, my Supermicro P6DBE board would always share an IRQ between a triple channel Mylex extremeRAID 1100 controller and one of the channels of a dual channel ZX348 ethernet card. When this happened, I would always see about 20% dropped packets on the ethernet channel sharing the IRQ. Manually overriding the IRQ assignment so that the RAID controller didn't share an IRQ with anything solved the problem. None-the-less, if there is no obvious evidence of odd behaviour, IRQ sharing is perfectly fine. However, if things are clearly not performing as they should, investigating potential IRQ sharing problems is not a bad idea. ...Sandy > Regards > S. > On Tue, 14 Sep 2004 18:56:18 -0600, Gary Aitken <[EMAIL PROTECTED]> wrote: >> On my 4.10 system, I added in a third ethernet device. >> >> However, I see from dmesg that the irq assigned is shared with my >> scsi controller: >> >> de1: <Digital 21041 Ethernet> port 0xf880-0xf8ff mem >> 0xfdfffc00-0xfdfffc7f irq 9 at device 16.0 on pci0 >> bt0: <Buslogic Multi-Master SCSI Host Adapter> port 0xfcec-0xfcef >> irq 9 at device 17.0 on pci0 >> >> Since the driver was already present, things went ok, in the sense >> that the system booted and scsi devices still work. >> >> 1.
