Re: IGB driver not getting Rx interrupt

Hi Adam,

I am pretty sure now that Fiasco's ISR is not getting invoked. I put a
printf in the following interrupt handler in fiasco's
src/kern/ia32/dirq-ia32-ux.cpp.

----
extern "C" FIASCO_FASTCALL
void
irq_interrupt(Mword _irqobj, Mword ip)
----------

And it never gets invoked.

You suggested in your last e-mail to "check whether the card is
reporting a pending interrupt". But I dont really know how to do that.
Is there some way in JDB to do that?

Regards,
Shashi Sharma
