Intel EEPro 100 with kernel drivers

Intel EEPro 100 with kernel drivers

[Thomas Langås]

Hi!

We've got a lot of machines with the eepro 100 from intel onboard, and when
we try to stress-test the network (running bonnie++ on a nfs-shared
directory on a machine), the network-card says "eth0: Card reports no
resources" to dmesg, and then the "line" appear dead for some time (one
minutte or more). What can be done to remove this error? NFS timesout with
this error (obviously)...

I actually have the same issue but I am not seeing any performance
loss. I do extensive NFS transfers as this box also stores a software raid
array, and aside from the kernel message, I am unaffected.

- From what I understand the problem is a hardware bug, and I believe I read
somewhere that by forcing the network card to use its own IRQ and not
having it share an IRQ will alleviate this problem.

Hope this helps ....

On a side note I run this nic on about 10 production web servers running
fbsd 3.5 receiving extensive traffic loads and have no problems with them
at all.

We found that using the intel e100 driver
instead of the eepro100 eliminates these
errors - YMMV of course -

I've now tried the Intel driver, no help, still get the NFS timeouts (the
intel driver doesn't output anything to dmesg, so it's no way of telling if
the same things occur as in the eepro100 stock-kernel driver). 

This is how I do the test:

NFS share a filesystem
NFS mount it on another box (not running intel e100 nic)
Start bonnie++ on the box that has mounted the nfs share

After 10-20mins, the first NFS timeout comes (which means the card is out of
resources, and "halts" for a bit). When the card becomes out of resources,
it seems like it uses a few minutes before it comes online again, no wonder
why, tho.

Has anyone got any suggestions on how to start tracking down, and maybe
fixing this problem?  Or, is this a hardware error?  Or maybe a firmware
error?  Should I start contacting Dell and tell them that's there's a
possible error in their PowerEdge 2550-series?

Well, with eepro100 the start may be the following:
1. When the card stalls, start ping from that host.
This way you ensure that you have something in transmit ring.
If it's transmitting that stalls, you'll get a message from netdev watchdog.
2. If ping works, then your problem appear to be pure NFS one, i.e. inability
of NFS to recover from network operation disruption.
3. If ping is able to transmit, but not receive (you may check it by
tcpdump), then we have a receiver problem.
We'll think what to do then.

4. In any case, running eepro100-diag from scyld.com at the moment of the
stall may give some useful information.
5. In any case, searching eepro100 mailing list archive on scyld.com is a
good idea, you may learn what other people observe/do.

Guys. This is Network section of my config:
#
# Networking options
#
CONFIG_PACKET=y
# CONFIG_PACKET_MMAP is not set
# CONFIG_NETLINK is not set
# CONFIG_NETFILTER is not set
# CONFIG_FILTER is not set

I work on this config (2.4.13) now and my machine has eepro100.o loaded.
Now I test it. This problem is appear when some options of IP section is
enabled. Now I can't say which of them. (I think SYN or MROUTE but it's
my assumption).

And, I mean anything, network-wise. There seems to be a timeout somewhere,
because after some time, everything resumes back to normal again.

OK, I'll do the test again, and run the eepro100-diag. Any special options
you want me to specify?

OK, I'll search... :)

If the operations stall just for few seconds, it's perfectly ok.
If after a few second stop the card itself resumes to operate normally, but
NFS operations are blocked for much longer time, it's NFS problem.
If the card itself stops operation for a long time, it needs to be fixed.

Yepp, and sorry, I ment, I tried pinging from client-side.

Ok, it seems like the stock-kernel-driver hangs much longer than the
intel-driver (intel driver did only hang for a few sec when I tried just
now).

I had some trouble with an Intel STL 2 board and the onboard EEPRO100.
Samba worked OK but it always got stuck on NFS transfers.

There was a bug in the older BMC firmware, so the eepro100 detected
some NFS frames as "TCO" packets.
(http://support.intel.com/support/motherboards/server/ta_353-1.htm)

If you use the e100 driver, you can look at 
/proc/net/PRO_LAN_ADAPTERS/eth0.info
If the "Tx_TCO_Packets" entry isn't zero after NFS times out,
this may be your problem.
With the eepro100 driver you will only see overruns with ifconfig.

If this is the case, you may want to check for a BMC (board management 
controller) software update.

Well this doesn't look exactly the same as on the system I had problems with.
But your Rx_TCO_Packets counter is  1, so this may be related
(I also got Rx overrun errors). It may be that your BMC receives the packet
and simply chooses to ignore it because it is no valid server management 
packet.

Could you make another test and take a look at the eth0.info ?
I could reproduce the problem when copying a large file over NFS, but not 
when transferring it via ftp. Try this a few times.
If you can reproduce you network card being stuck only when using NFS and 
having Rx_TCO_Packets > 0 after it is stuck, this is it.
Then you either need tu upgrade your BMC firmware or add another network card,
which doesn't eat NFS packets.

I'm testing now, however, running eepro100-diag gave me some interessting
output:

Sleep mode is enabled.  This is not recommended. Under high load the card
may not respond to PCI requests, and thus cause a master abort.

How do I disable sleepmode? I've never even enabled it.

The sleep bit is sometimes enabled by default (it was for me).
You can clear it with eepro100-diag (I think it was the -Gww option).

The documentation for eepro100-diag is somehow sparse, but
clearing the sleep bit was discussed on the eepro100 mailing list at 
scyld.com in great detail. You might want to browse the archives there.

It should be Rx_TCO_Packets, not Tx.
The problem described in Intel's advisory is related to incorrect processing

But if it's this bug that's triggered with NFS-traffic, then the counter
should be increasing with every timeout, right? Not just one time. I get a
lot of timeout and the counter is still just 1.

I'm going out to buy me another NIC and try tests a bit systematically, and
report back with the results afterwards.

The Rx_TCO_Packets counter should increase at each timeout you get,
so this looks like another problem.

I have got two servers with two different EEPRO100 network cards. 
One works better with the eepro100 driver, the other one seems to favour the 
e100 driver :-)
Both cards are working flawlessly now, however I was close to buying new NICs 
because of the problems like command timeouts, no resources messages and NFS 
timeouts.

A datapoint that might be interesting:

I run four of these buggers with eepros as Internet-Interfaces for
heavy traffic (30-80 MBit sustained 24/7) under 2.2.19. Not a single
glitch on each of these boxes. The machines have two PIII/1GHz each
and a (custom built) SMP kernel based off RH 2.2.19-6.2.7

Which kernel version, which eepro100 chip ?

Re: Intel EEPro 100 with kernel drivers

[Michael Rozhavsky]

Hi,

We have exactly the same problem with 2.4.9, 2.4.10 and 2.4.13, so
We had to switch to Intel's driver.

from 'cat /proc/pci'
  Bus  1, device   1, function  0:
    Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 8).
      IRQ 9.
      Master Capable.  Latency=64.  Min Gnt=8.Max Lat=56.
      Non-prefetchable 32 bit memory at 0xff8fe000 [0xff8fefff].
      I/O at 0xdf00 [0xdf3f].
      Non-prefetchable 32 bit memory at 0xff600000 [0xff6fffff].

It is Intel i810 motherboard with NIC onboard.

but Intel's driver (e100-1.6.22) says on boot: 
eth0: Intel(R) 82559 Fast Ethernet LAN on Motherboard

the chip is:
GD82559
L021LP51

We have this problem when nic is under high traffic.

Is there any other information that can help you to track the problem?

P.S. I can reproduce this problem any time.

We have almost the same problem, except it totally locks up the
computer. Light network utilization is ok, but heavy traffic does the
effect.
No syslog reports, even keyboards leds won't light up (numlock, etc).
Rebooting helps for a while. We had to install another network card for
a workaround. I've tried kernels 2.4.10 and 2.4.12.

The network card is integrated at the motherboard.

Sounds like this might be the same problem that we are experiencing
here. The nic does get a high load of traffic immedeately when it has
booted up.

No messages of anything remotely wrong whatsoever, even after
setting the highest debug level in the eepro100 driver.

I searched a bit and seems some users have had same kind of problems
with 10Mbit network with high amounts of collisions, just like ours is.
