Ah nice, I found a hole in time to try it as well. I just rebuild a kernel
and rebooted. During the reboot I found what you write above. :)
Anyways, the attached patch makes it work indeed as you found yourself as
well in the mean time. :-)
I tried just deleting the call itself at first, but the module is compiled
with warnings treated as errors and barfs about a defined but unused
function. So in the patch you'll find the entire function removed.
Let me know about anything else I can do. I don't have the necessary test
equipment at home, so normally I'll need to find a time window to test
things. But I'm more then willing to.
The version I patch is the following by the way, from 8.0-RELEASE-p2:
/*$FreeBSD: src/sys/dev/e1000/if_em.c,v 188.8.131.52.2.1 2009/10/25 01:10:29 kensmith Exp $*/
Thanks so far!
