I have a FORE PCA200E ATM card. We use LAN Emulation, so my
interface device (after atmsigd, ilmid and zeppelin are started) is
lec0. When I have only tcp/ip networking going, ifconfig looks like this:
lec0 Link encap:Ethernet HWaddr 00:20:48:08:C7:9B
inet addr:129.22.238.211 Bcast:129.22.255.255 Mask:255.255.0.0

RX packets:66 errors:0 dropped:0 overruns:0 frame:0
TX packets:66 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
When ipx_configure --auto_interface=on is set, and I ifconfig lec0
for tcp/ip, I start getting a lot of these messages:

over and over. ifconfig looks like this:

After a variable amount of time like this, with the network number
collision errors, my machine will "crash". It becomes unresponsive at the
keyboard and mouse, and I cannot switch virtual consoles nor to or from X
Windows. If I am at console at the time, I see a very fast stream of
gibberish (as if cat'ing a binary). /var/log/messages from this time also
contains gibberish with no unusual message before this other than the
repeated Network number collision errors. I have experienced this in both
2.2.14 (with ATM patch 0.59) and 2.3.99-pre5 (with ATM patch 0.76).
I realize setting ipx_configure --auto_interface=on will stop the
IPX interfaces from being automatically being created on ifconfig, and
subsequently get rid of the problem, but somehow I don't the crash was
intended. Additional information is, of course, available on demand.
