That's clear - but I wasn't sure if there's really a problem whith shared interrupts.
In the meantime I swapped my "new" NICs with some via-rhine based cards and experienced the same problem when sharing interrupts. (so I proved that there's no bug in my freshly ported driver...) Concluding I can say that RTnet (+RTAI) can't be used on NICs which share their interrupt with non-realtime NICs (which are in use at the same time). Klaus Zhang Yuchen schrieb:
The most straightforward way: Open your box, plug one NIC to another PCI slot. Keep on trying, until the two use dfferent IRQ. Yuchen
