Description Christopher Johnson 2006-11-04 10:56:48 EST
Description of problem:
A new installation of FC6 on Prasario 2100 booted fine.  Has built-in ethernet
(eth1), but I configured and used wireless card (eth0) instead, leaving wired
interface unconnected. Installed updates via yum. Went to shutdown system, and
got an oops referencing natsemi (eth1 driver).

Version-Release number of selected component (if applicable):
kernel 2.6.18-1.2798.fc6

How reproducible:
Good question.  This is a new install of FC6 last night I will continue to use
the system and update this record.

Steps to Reproduce:
1. Install, boot, use FC6, leaving wired ethernet disconnected. 
2. Shutdown system.
3. get an oops during shutdown
Actual results:
Oops screen.

Expected results:
Clean shutdown.

Several boots and shutdowns without incident.  But leaving the system up for
about 20 hours and the oops happened at shutdown again.  Some registers were
different, but the address, trace modules and offsets, error message and current
script/line were the same.  So 2 days, 2 kernel crashes on shutdown.

This looks like the same problem that exists with the tulip driver upstream
(which would make sense since they have similar origin).  Basically its a race
between driver timers, interrupts and dma.  

It seems like it's not something you can easily reproduce but you might be able
to if you had a lot of traffic going on the device and then called `ifdown eth1
&& rmmod natsemi`  I've also seen reports of `ifdown eth1` combined with a
constant `ethtool eth1` running in the background.

I'll try and put together a patch that is similar to the tulip one and see if
that helps.  Would you be willing to try and reproduce this on your laptop?
