v1.06 -- transmit timeouts again

Hi,

We are able to _consistently_ reproduce transmit timeouts in our
eepro100.  The driver version is "eepro100.c:v1.06 10/16/98" from a
2.2.5 Linux kernel.

Here are some log messages:

eth0: Transmit timed out: status 0050  0000 at 24762714/24762730 command 00020000.
eth0: Trying to restart the transmitter...
eth0: Transmit timed out: status 0050  0000 at 24762730/24762746 command 000c0000.
eth0: Trying to restart the transmitter...
eth0: Transmit timed out: status 0050  0000 at 24763766/24763782 command 00020000.
eth0: Trying to restart the transmitter...
eth0: Transmit timed out: status 0050  0000 at 24763782/24763798 command 000c0000.


Our hardware:

	- Dell PowerEdge 6300 Server
		400 MHz Quad CPU Pentium II Xeon (512KB Cache each)
		1 GB RAM
		eepro100 card (running at 100 MBps)

The kernel is compiled with SMP support.

Our code makes 16 multicast connections.  Everytime we run this
particular application we get the "transmitter timeouts" that cause the
machine to lock-up while the program is running.  We do eventually
regain control so we haven't had to reboot yet.

Note that we have only experienced this problem on our Linux eepro100
systems.

I wont't post the program since it is a rather large and complicated
application (TAO's CORBA Event Channel) and it would be difficult to
"slim down" to a managable size.  The source is available if needed.

Please CC me since I am not subscribed to this list.

Thanks for any help or suggestions,
-Ossama
