Hi,
I've been noticing some strange problems with the built-in nfe0
interface on my desktop. Actually I've seen it on two such
computers, but the description below is for my current desktop PC.
The PC is running `cvs up -dP -rOPENBSD_4_1' built. I'm including
netstat, ifconfig output[1] and dmesg below[2].
I've noticed that once in a while the nfe0 interface will stop
sending and receiving data. At this point I can not make it work
again. The only solution I have is to reboot the box. I have
installed a dc0 card in the box since. The problem seemed
intermittent and not reliably reproducible. But I think I found
a way to reproduce this problem on demand (at least for the time
being). I have an ssh session to another box, on which I run
'/usr/bin/nm somelib.so'. After a page or two of output the
terminal "hangs". At this point nfe0 becomes unresponsive.
I switch to the dc0 interface and the terminal finishes the output.
Running the nm command while using the dc0 interface doesn't cause
any problems.
Interestingly enough, if I redirect the output of nm to a file
and subsequently cat the file the nfe0 interface doesn't seem
to exhibit the same problem.
I am not sure how to diagnose this problem further. I've enabled
debug on the nfe0 interface (/sbin/ifconfig nfe0 debug), but don't
see any output.
Any and all suggestions are welcome.
