Hello all,
I posted this bug on Redhat's Bugzilla
(http://developer.redhat.com/bugzilla), and thought about informing you
about it too.
I'm not subscribed to this list, so if anything relevant comes up, please
CC it to me..

I have loaded SMC Ultra ethernet module successfully with
2 different computers. You can't connect to other computers
from them - the network doesn't work. When I try to remove them
with rmmod, there will be a kernel oops (eth0's are epic100's on the
both computers):

After that, weird things happen:
-----
[root@test11 /root]# lsmod
Module Size Used by
lsmod: QM_INFO: No such file or directory
-----
Any ideas?
------- Additional Comments From 09/29/99 17:01 -------
1) Module loads fine. "ifconfig" behaves as expected. "ping" to self
succeeds. "ping" to other machine fails w/ 100% packet loss.
2) Compiling into the kernel (ie non-module) doesn't help.
3) Also happens on eth0.
4) "wd" also affected. No segfault on rmmod, though.
5) Other modules dependent on 8390 (eg "ne") behave as expected.
Notes: 3 different SMC Ultra (16bit/ISA) and 1 smc ?? (works with "wd"
module in RH5.x) cards tested in 2 machines.
