Looks like IRQ problem. Can you see IRQ handler being called? I.e. doesn the counter in /proc/interrupts increment?

It should be, though I haven't used N2 card for a year maybe. Still, other cards (c101 and pci200syn) share the same low-level driver core, I know people with c101 (not sure about their kernel versions) and I personally use pci200syn with latest 2.6 kernels.
There are some issues wrt Frame-Relay code (no PVC list locking, there is some small possibility of kernel panic etc. while removing a PVC on live interface - will fix when time permits, problem never reported). -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
