It's probably not a mis-configured IRQ then.
Not sure -- see below.

No delays in Linux?
This one has me stumped. Mike?

I started to debug the if_ep.c driver in the kernel. I have some
experience in kernel ports and will see what I can do. I already
found that the problem are the outbound IP pkgs. For every pkg
the routine if->watchdog gets called for a missing interupt.
So the problem isn't in user-land (e.g. routing or ARP or DNS),
it's in kernel-land. Is there someone who is "in charge" for
that driver code or someone who can offer the internal programmers
manual for that card (3C589D)? Thx.
Mostly I'm working for UNIX SVR4.x system software w/o the kernel
source -- it's nice to have the source of FreeBSD.
