lspci output:

I made a list of driver versions that showed the problem so far:
| Tulip driver version 0.9.11 (November 3, 2000)
| Tulip driver version 0.9.13 (January 2, 2001)
| Tulip driver version 0.9.13a (January 20, 2001)
| Tulip driver version 0.9.14 (February 20, 2001)
There's one version I never had problems with:
| Tulip driver version 0.9.5 (May 30, 2000) (from 2.4.0-test1-ac10)
Of course I'm not 100% sure, but I ran 2.4.0-test1-ac10 for nearly 6 months on
that machine, without a single Tulip problem. All other versions caused
problems in a much shorter timeframe.
BTW, do you want me to try 1.1.2?

I can confirm that this patch fixed my problem. Sometimes transmission still
times out, but the driver recovers automatically within 3 minutes. The machine
has been up for more than one month.
Still no comments?

I did some more investigations...
If a transmit timeout happens on a 21041, the current code changes the
interface medium:
1. If 10base2 (if_port = 1) and no 10baseT link beat, stay on 10base2 (1)
2. If AUI (2) and no 10baseT link beat, swith to 10baseT (0)
3. If 10base2 (1) or AUI (2) and the 10baseT link beat is present, swith to
10baseT (0)
4. If 10baseT (0), switch to 10base2 (1)
To me it looks like these rules are flawed. Apart from the fishyness of the
first two rules, rule 4 unconditionally switches my interface to 10base2, while
I still have a 10baseT link beat ((csr12 & 4) == 0)!
As removing this media change code didn't help, I modified the code in the
following way:

It still takes a few minutes to recover, but at least it recovers
automatically, and within the TCP timeout limit, so no connections are lost.
I tested this by transfering several gigabytes across the network using netcat,
and it always recovered without needing manual intervention.
So I suggest the following patch:

+++ linux-2.4.20/drivers/net/tulip/tulip_core.c Sun May 11 11:31:29 2003

}
Any comments?
BTW, is there a version of the new de2104x driver in 2.5.x available for
2.4.20?
FYI, the debug code commented out with `#if defined(way_too_many_messages)'
doesn't work, but I haven't found out yet why exactly it crashes the kernel,
though.

Hi Jeff,
Under heavy network activity (e.g. downloading ISOs), my Tulip card (D-Link
DE-530+ with DECchip 21041) still goes down with 2.4.20.
Suddenly I start getting messages of the form:
| NETDEV WATCHDOG: eth0: transmit timed out
| eth0: 21041 transmit timed out, status fc660000, CSR12 000051c8, CSR13 ffffef01, CSR14 ffffffff, resetting...
| eth0: 21143 100baseTx sensed media.
and the network no longer works. Sometimes it automatically recovers after a
while (without printing additional messages), but usually I need to do a manual
ifconfig down/up sequence to revive the network.
The register values may differ. Last time I saw these, with their respective
number of occurrencies:
1741 x status fc260010, CSR12 000000c8, CSR13 ffffef09, CSR14 ffffff7f
581 x status fc260010, CSR12 000002c8, CSR13 ffffef09, CSR14 ffffff7f
20 x status fc260010, CSR12 000050c8, CSR13 ffffef09, CSR14 fffff7fd
6 x status fc260010, CSR12 000052c8, CSR13 ffffef09, CSR14 fffff7fd
28 x status fc660000, CSR12 000051c8, CSR13 ffffef01, CSR14 ffffffff
Once it printed
| eth0: 21041 media switched to 10baseT.
after which the network seemed to work again for a few minutes.
I also got 27 times
| eth0: No 21041 10baseT link beat, Media switched to 10base2.
which I find, together with the zillions of `21143 100baseTx sensed media'
messages very strange, since the card is 10 Mbps-only and connected using UTP
to a 10 Mbps-only Ethernet hub (D-Link DE816-TP).
Driver startup:

The machine is a PPC box (CHRP LongTrail).
Is there _anything_ I can do to help resolve this problem? Which debug options
do I have to enable to give you more information?
Thanks!

Apparently this problem is still present in 2.4.20. It's been many months ago I
saw it, though.

^^^^^^^^^^^^^^^
ifconfig down/up fixed the problem.
