Hi,

I try to install/configure a quad port Compaq NC3134 equipped with the
NC3135 module into a server system. The NC3134 is a dual board, NC3135
is a module installed on top of the NC3134 which provides 2 extra 10/100
ports for a total of 4 ports. The board is a PCI 64 bit card. All the
four ports are i82559 chipsets (eepro100).

The server is a dual PIII 933 MHz equipped with a ServerWorks based
chipset. The system has 512 MB RAM and a 36 GB SCSI hard drive. This
system is also equipped with dual on-board i82559. It makes a total of 6
i82559. The server runs RedHat 6.2 over a 2.2.17 kernel.

The problem resides in the fact that 2 NICs are not working well. I got
this message:

    eth0: IRQ 23 is physically blocked! Failing back to low-rate
polling.

It looks like an IRQ/IOAPIC problem. The faulty ports (both module ports
on NC3135) are sharing IRQs with their parents (main ports on NC3134):

               CPU0       CPU1

NMI:          0

 The board finally works but give a really slow rate:
