Hi,
I ran it for over an hour without cpufreq and powerd without
problems with just one client. I will recompile the kernel tomorrow
(cant load it as a kld for some reason) and see if I can trigger it.

I do the umount/mount as its a good way to make sure the file is not in cache.
What version of nfe are you running ? If its older than
% ident /usr/src/sys/dev/nfe/if_nfe.c
/usr/src/sys/dev/nfe/if_nfe.c:
$OpenBSD: if_nfe.c,v 1.54 2006/04/07 12:38:12 jsg Exp $
$FreeBSD: src/sys/dev/nfe/if_nfe.c,v 1.21.2.5 2008/04/17
04:22:32 yongari Exp $
perhaps try that on your machine to see if it helps. Prior version
did not work very well for me at all. Not sure if it will just
"work" or you need to do a full cvsup buildworld/buildkernel.
