SubjectOnce again an eth0: transmit timeout problem, with 8319too
Hi,

I originally posted a similar bug report under
http://sourceforge.net/tracker/
index.php?func=detail&aid=440357&group_id=3242&atid=103242

but as I guess that this list is a much more appropriate place for
it, here it goes, slightly modified:

---cut---
Hello,
I've tried reading LKML archives etc for this problem
and the advice usually is "fixed in the latest kernel
versions". So I've tried 2.2.18 (not with the 8139too
driver but Don Becker's, which is IIRC actually known
to have this bug) and the 8139too driver with 2.4.0
upwards to 2.4.6 and 2.4.6ac2.

After bootup, if I do something network-wise which takes up more
bandwidth than ICQ and IRC, soon I get in the syslog:

NETDEV WATCHDOG: eth0: transmit timed out
eth0: Tx queue start entry 4346 dirty entry 4342.
eth0: Tx descriptor 0 is 00002000.
eth0: Tx descriptor 1 is 00002000.
eth0: Tx descriptor 2 is 00002000. (queue head)
eth0: Tx descriptor 3 is 00002000.
eth0: Setting half-duplex based on auto-negotiated
partner ability 0000.
and this makes the network stop for a few seconds
before the Watchdog resets the ethernet card and makes
it work again, dropping my download throughput from
approx. 400 kB/s to 10 kB/s. Ugh.

I've also tried just setting the #define RTL8139_DEBUG
1, at least in the more up-to-date 0.9.18 (without the pre4) from
Jeff Garzik's Sourceforge project site, but this gave very strange
results (like the driver displaying it had 100Mpbs and Full Duplex,
while the card's connected to a normal 10 Mbit hub (which I guess
can
only handle half-duplex!?)

OK, without having enabled debug info I'll also attach
the lspci -vvv and the rtl8139diag output as indicated in the
8139too.c
source file.

If you need further information, please do Cc: me as I'm not on this
list,
and while I'll check the archive answers will be faster with a Cc.
I'll answer almost everything (because I tried switching
motherboards, processors, a new RTL8319C, network
cables... and I always got the same error. Argh. It
also happened on my old SuSE distro as it does now on
Debian unstable. It's probably some kind of "user too dumb" error
:-(

So, now the output of lspci -vvv:

and now the rtl-8319-diag-output (unfortunately it was
impossible to time this so that the output is from the
exact moment where it resets the card):

BTW, why it says full-duplex mode above, I don't know. Especially

It would be so cool if you could help me out here :-)
