NETDEV WATCHDOG: eth0: transmit timed out

Same old story, bugger still does it.  Have to set the link down/up to
get it running again.  I had to reset two systems tonight, one up for
~60 days, one up for two days.  Both have this card.  Unrelated traffic.

This is kernel 2.4.0-test13-pre4

I missed your earlier mails, could you resend the details? 
I'm interested in the output from

	tulip-diag -m -a -f

before and after a link failure.


I'm aware that the tulip drivers doesn't handle cable disconnects and
reconnects with MII pnic cards. I have a patch for that problem, but it
affects _all_ MII tulip cards, and thus it won't be included soon. If
tulip-diag says "10mbps-serial", then you have run into that bug.

Here's the before, when the after happens..

This particular one is on a crossover @ 100 FD with a pcmcia tulip

The other machine I had reset tonight was on a crossover w/ cisco 3640
iirc.

I have the same transmit timeout problem, but with a D-Link via rhine
board. I'm running -test10, and it seems to happen under high
(interrupt?) load with both heavy disk and network
activity. Interestingly, it appears to happen more often when the other
end of the network activity is a 10BaseT link. I'm using a Netgear
dual-speed hub.

Do you think these might be related?

Re: NETDEV WATCHDOG: eth0: transmit timed out

[Darryl Miles]

I am getting complete lockups of the NIC, up/down the interface doesn't
restore it.  rmmod/insmod of ne2k-pci and 8390 doesn't restore it.  A
reboot does.

The m/c with this card in isn't normally highly loaded on the network,
but under heavy load it will lockup completely (fairly reliably I
suspect).  I have also had this problem with 2.4.0-test11, I had traced
it to ei_tx_intr() in so much as it was calling the
"ei_local->stat.collisions += 16;" line.  This is 8390.c:635 in 2.4.0.


The log below shows the time I had reloaded the modules trying to bring
it back to life.

NETDEV WATCHDOG: eth0: transmit timed out

[Caleb Epstein]

	I am seeing the following error after my machine has been up
	for a while.  My eth0 is connected to a switched, local
	subnet.  There is not a lot of traffic on the interface, maybe
	a few 100 Mbytes or so.  Taking the interface down and then up
	again fixes the problem (until it happens again :)

	Here is the relevant section from my kernel log

	Then a similar dump repeats until the interface is recycled.
	It appears that the interface was not functioning for some
	hours before the message was generated, and it was my attempt
	to ping a host on the local subnet that caused the NETDEV
	WATCHDOG error to be generated (e.g. the card locked up, but
	the kernel didn't notice until I tried to send something on
	the wire).

	The card is:

	eth0: 3Com PCI 3c900 Boomerang 10Mbps Combo at 0x1400,
	00:60:08:bd:ab:0e, IRQ 9

	I am running kernel 2.4.2, and have seen this error in 2.4.1
	as well; not sure about 2.4.0.  I do not ever recall
	encountering this error with the 2.2.x kernels, though my
	network topology has changed, but not my hardware.  I know of
	at least one other person who gets this same error with a
	eth0: 3Com PCI 3c905B Cyclone 100baseTx card.  The system is a
	P2-300, 128 Mb RAM, running various versions of Linux very
	happily for 3 years.

	FWIW, IRQ 9 is shared with the bttv module, though the network
	lockup doesn't seem to be related to my use of that module.  I
	was using xawtv last night while the interface was stil active
	and functioning.  The lockup happened this morning.

	Sorry for the long-winded post.  Is this a known bug?
	Anything I can do to help track it down and squash it if so?

My guess would be that the driver has decided there's no
link beat on the 10baseT interface and has flopped over
to using 10base2.  A fix for this exists in 2.4.2-ac5+,
in the zerocopy patch and in

	http://www.uow.edu.au/~andrewm/linux/3c59x.c-2.4.2-pre4.gz

but not in 2.4.2.

You'll need to use

	options 3c59x options=0

in /etc/modules.conf to pin the driver down to using a 
particular physical interface - disable autoselection.


So could you please upgrade the driver?  If problems
remain, please send me a report, as described in the
final section of Documentation/networking/vortex.txt.

Thanks.
