Hi,

maybe is an off toppic, but probably some like me has this issue. I have a=
=20
mainboard with several PCI and two PCIe. I can configure the PCIe to use wi=
th=20
rtnet and xenomai without any important problem.

The mobo has an eth and firewire and vga incorporated, so the pci are free.=
=20
But now, I would like to add a pci network card. I have three:
=2D on for our environtment
=2D two for the rtnet (two robot controlers)

and then I would like to have 4
=2D one for another network

The problem that I have and I don't know how to solve is that the new pci=20
network card share an irq with another device. So, in my case, I have =20
problems with this. With rtnet, I solve this using pcie devices, but now I=
=20
cannot.

I have configure the xenomai kernel following the FAQ, and I have tested to=
=20
assign an IRQ in the BIOS. But I have not be able to make the interface=20
works. I have delays in the interface, and google says ;-) that is a proble=
ms=20
of sharing IRQs with the eth. And I believe in that ...

So, thinking that I would like to use this eth in a normal environment (not=
=20
rtnet,) but in a box using xenomai, some of you have some "magical" idea,=20
kernel parameter, etc to solve this issue?

Thanks in advance,

Regards,

Leo
