[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Tony Eckel]

Have an EliteDesk mini 705 G2 with identical issue and none of the fixes worked.
running Ubuntu 20.04.2 LTS
So it isn't fixed.

What do you need to troubleshoot this?

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Janno Sannik]

Just letting know that "iommu=pt" fixed my problem on HP Elitedesk 705
G2. There was not even a talk about test benching anything since I could
not even download a 100MB file using 300Mbit/s internet connection. It
would lose connection without any logs. It however would recover with
ifdown/ifup.

This is not ubuntu, but (up to date) proxmox-ve v6.2-15 using kernel
5.4.65-1-pve which is based on debian.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Bob Lawrence]

I did not apply the patch in #13, but I did try disabling highdma with
ethtool (essentially what the patch makes permanent) and that had no
effect for me (at least not on the kernel I was using at the time). I
did try the patch in #40 and that had no effect for me either. The only
thing I've found that keeps my Broadcom 5762 alive without disconnecting
is the kernel parameter "iommu=pt". I'm just finally grateful to have
found a workaround so I can keep this server wired and not have to rely
on its wireless only.

I can't help but think we are chasing a moving target across so many
kernel versions since this issue was first reported.

[Toan]

Has anyone applied the patch to the tg3 driver that was shared in
comment# 13?  That one solved the issue for me.  If that was the real
fix, I'd like to inform the tg3 maintainers about it so that we can have
it patched in the mainline.  thanks.

[Bob Lawrence]

I'll also add that though I had previously tried iommu=soft with no
luck, trying iommu=pt as suggested by chithanh in post 70 does seem to
workaround the issue successfully. I'm not sure as to why that would be
the case as this is neither a VM nor a VM host, but since adding the
parameter to my kernel line and rebooting I've been running for several
hours with media continuously streaming. Without the parameter it would
only stream for a matter of minutes before dropping the connection.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Bob Lawrence]

Problem still exists with kernel 5.3.0-59-generic. Same machine I
reported on previously. Multiple kernel releases since then. Only change
with more recent kernels is that the connection recovers on its own
after a few minutes (as opposed to requiring a reboot). Still, the only
workaround that has any effect is to manually set the connection to
100mbps and half duplex. Pretty useless for a media server.

Example dmesg output when the problem occurs:

Still an issue here with Dell Latitude 5495 and Kernel 5.2.7.

I noticed that very much like similar problems I had with Realtek LAN,
it helped as a workaround to boot with iommu=pt kernel parameter.

A rtl8169 report was here
https://bugzilla.kernel.org/show_bug.cgi?id=14962 (and many others
exist)

[Paulo Abadie Guedes]

Thank you, Kai-Heng Feng. Really appreciate it.

Currently I'm under a lot of pressure at work. But I will try this in the
next days, to see if it fixes the problem for us. My network still have the
same condition and my previous kernel versions are still breaking. So, it
should be easy to reproduce.
Will write back reporting as soon as I can.

Thank you again,
Paulo

Same issue with HP EliteDesk 705 G2 MINI

Turned off all power saving options in BIOS.

Currently running 18.04 HWE EDGE (Linux 5.0.0-15-generic) compiled with:

CONFIG_TIGON3=m

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[James Johnson]

I have been experiencing this issue on an HP 745 G4 with the same BCM
5762 on several kernel versions from ubuntu 16.04 and up to 4.15.0-45.
On my system the network would immediately crash often before logging
in.  Occasionally I would be able to ping for several seconds before the
device would crash.

I have tried several work arounds in this thread although none were
successful. Setting iommu to soft may have increase the duration from 10
seconds to about 30 however I did not test this extensively.

I was able to upgrade to mainline kernel 4.20.7-042007 using uuku, and I
no longer experience any device instability. I'm not sure if this
specific patch was included in this release although it maybe useful for
those still experiencing crashes on Ubuntu 18.04

@paulo.guedes

Yes, removing and re-adding the modules as you describe does at least
recover eno1 without rebooting. Still, hardly a solution for what was
intended to be a headless Plex server. This happens every time I start
an mpeg2 tv stream through my plex box which is only about a 20mbps
load. Sometimes it happens immediately sometimes it goes for nearly an
hour.

Also, I compiled a custom kernel with the patch described in post #40.
It had no effect on the dropouts for me. They are still occurring.

Also, on the last crash, I caught it while it was happening and RX/TX
errors and collisions all went through the roof right before it went
"no-carrier".

Re: [Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[marc]

we're using this hp g1 thing primarily for torrent seeding and
gnuMotion...  so it is consistently getting ~5mb/s and pushing out 300kb/s.

the explanation on #60 might explain why this recipe is somewhat stable --
its always active.

i also havnt updated the bios - i wont have physical access for a few
months - but since others are saying it makes no diff ... think i wont
bother

- uptime/ 48 days
- RX/ 18tb
- TX/ 4tb
- 2 tg3 hangs ... and it restarted the driver on its own

Re: [Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Paulo Abadie Guedes]

Thank you.
I am still having the problem during our cloning process, although it's not
so frequent. Before the patch I applied, each and every transfer would
ALWAYS kick the tg3 bug.

Here it seems related to problems with NAPI. AFAIK, this is an approach to
handle interrupt bursts. NIC's work typically in bursts: a long time
without packets, then a very large stream of packets, then silence. This is
the common scenario.

Having interrupts to serve sporadic data is ok. But a burst of packets
trigger a burst of interrupts, which is not as efficient as just polling
the NIC (during the burst).

What NAPI does is (in a very very simplified way): it expects the first
interrupt from the network, then switches off interrupts, poll the NIC (up
to a limit) until there are no more network packets, or the "work quota" is
exhausted, what happens first. Then it turns on interrupts and the cycle
repeats. This quota (sorry, don't remember the correct term) is very
important to prevent the kernel from being stuck just serving packets.

What's happening is (my understanding) that something went wrong during
this process and the tg3 driver gets stuck.

A colleague told me that it's related to the broadcom driver.

Please try this workaround. Remove the two drivers, then reload "broadcom"
and "tg3" in this order. Maybe then your network will restart.

sudo modprobe -r broadcom tg3
sudo modprobe broadcom
sudo modprobe tg3

Please tell us what happens when you try this. It won't solve the problem,
but perhaps it helps.

Regards,
Paulo

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Bob Lawrence]

Confirmed that this is still an issue on 18.04.1. I have an HP 705 G1
with the Broadcom 5762. In my case it's a Plex server. Whenever I try to
stream something the interface goes "NO-CARRIER" and the only way to
recover is to reboot. I've tried disabling highdma, tso and gso using
ethtool, iommu=soft kernel parameter, and forcing every combo of
1gbps/100mbps & half/full duplex. Nothing seems to workaround the issue.

Yea I saw the same issue on Gigabits ethernet. I raised the issue [1] to
the tg3 maintainers.

Do you use 5762?

Actually with 4.19.6 and Bios HP V02.31, Tg3 still crash with 100Mbps or
1 Gbps

Logs are still the same

[Wu]

Hi,

the commit 3a498606bb04af603a46ebde8296040b2de350d1 mentioned in #54 has
been integrated to my current customized RHEL(CentOS)-7 for a certain
time. This fix can also be found in the new kernel releases, however
even with the 4.19 mainline kernel the bug is still not solved.

- For a 1Gbps ethernet, nothing was changed with this commit. There was
immediately the crash after some transmission.

- With the 100M ethernet, the crash is not very often triggered even
without the above fix. I cannot judge yet.


Best regards

Sorry for multi posting, didn't saw the 4.15.0.9 kernel before... :)
TG3 still crash, but not too early... I made several video on full HD + several 
speed test before losing connection; (FTTH here, my download speed is about 290 
Mbps)

Re: [Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Paulo Abadie Guedes]

Hi Kai-heng,

Here are the test results we got.
Kernel 4.15.0-14-generic failed. Transmit queue timed out. The dmesg output
is attached. The tg3 module crashes in a few seconds right after opening
the user session (e.g. about less than 10 sec).

However, kernel 4.15.0-9-generic worked like a charm. It boots and brings
up tg3, the Ethernet link is working and the module seems stable. We tested
it to download a few gb, an Ubuntu image, play videos for a few hours and
the like. Not even a single crash was observed. The dmesg output for this
working kernel is attached also, because maybe it might help you to sort
out what's different from one kernel to the other.

Would you like us to test another image? Or to gather more information?

Regards,
Paulo

We tried this same version yesterday and the bug was still present.
Actually it looked worse, because the machine crashed faster (maybe was
just an impression). Will collect logs to report this properly soon, in a
few hours.

Folks,

tg3 maintainers are waiting for the test result. Hopefully it can fix
the issue.

Re: [Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Paulo Abadie Guedes]

Ok, I'll check it out. Thank you very much!

By the way, we downloaded and tested one of the Deb packages you created,
and it worked quite well. Will check which one was exactly before
reporting  (almost sure it was the one for xenial).

We managed to reproduce the issue easily by booting into pxe and, after the
nic was started (trying to get an ip), we reset the machine and booted into
Ubuntu. There is a huge difference by doing this and doing a cold boot,
directly into Ubuntu.

My hypothesis is that pxe setups the nic in a way that is not the default,
by changing one (or more) of the config bits for some register. This same
bit(s) is/are not being touched by the tg3 driver without patch. This way,
a boot may work sometimes, maybe due to default values not being set by the
kernel module tg3 (and being set by pxe code, if it executed before Linux
is loaded).

Anyway, the unpatched kernel breaks very quickly, while the patched kernel
you provided worked out very well. This happens after running pxe.

I will check your links soon and return with our results in the next days,
hopefully this weekend or next week.

Thank you,
Paulo

  The tg3 broadcom network driver that binds with chipset 5762 goes offline
and unable to recover (even with tg3 watchdog timeout) when network
transmit is under high load.  Call trace:
  https://launchpadlibrarian.net/204185480/dmesg

  When this happens, only a reboot would be able to fix it.  Sometimes,

  disabled TSO, GSO etc... with ethtool and the bug still surfaces.
  This bug may be related to the integrated Firmware.

  Here is the procedure to replicate the issue because it is hard to
  replicate it under moderate network load.

  1. Bootup a machine with a broadcom 5762 NIC (ie. HP DeskElite 705) using
a Ubuntu/Kubunu Live CD 14.04-15.04.
  2. from another machine: start 5 sessions, repetitively copy (scp with
public key authentication) a 70 meg file back and forth to the tg3 machine
in each session. (not sure if this is necessary)
  3. create a 1GB file on the tg3 machine, with something like dd
if=/dev/urandom of=/my/test/file bs=1024 count=$((1024*1000))
  4. from another machine: repetitively scp copy that 1GB file from the tg3
machine. This can be done with something like:

  while [ 0 ]; do
 scp -i /my/scp/private.key u...@ip.of.tg3:/my/test/file /tmp
  done;

  Networking will mostly goes offline in about 10-30 minutes.

  WORKAROUND: Add udev rule to make the changes permanent in
/etc/udev/rules.d/80-tg3-fix.rules :

The kernel was compiled in Bionic, so it has wrong dependency on Xenial.
I built a new one, please give it a try:

[marc]

i recently got one of these EliteDesks. tg3 locks up like once a week;
seems to happen when flexget adds a bunch to transmission ... it spikes
the TX... and boom. i just installed the patched kernel now. thanks
yall.

Thank you, we will try it as soon as possible.

Currently I'm on vacation, and will not be able to test it until about
March 5 (2 weeks from now). But as soon as I test it, I'll let you know
about the results.

It would be great if someone else could try it too.

Thanks,

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Paulo Abadie Guedes]

Hello, this thread has a patch that solved the bug (for me).
https://www.mail-archive.com/netdev@vger.kernel.org/msg189347.html

The patch is here:
https://www.mail-archive.com/netdev@vger.kernel.org/msg189923/0001-tg3-Add-clock-override-support-for-5762.patch

I tested this patch on the following kernels and situations.

1) Stable kernels 4.13.3 and 4.15 crash without the patch (plus all
other versions tested). Patch is not merged yet in the main linux
branch, until (and including) 4.15 (stable).

2) Stable kernels 4.13.3 and 4.15 work great with the patch: no timeouts
on tg3. Fast transfers on gigabit links and 10/100 links.

3) I wrote to the patch author, mentioned my results and asked when it
will be merged on Jan 31 (10 days ago). Still waiting, probably the
author is currently quite busy.

4) A lot of tests performed during weeks. The last session took about
one or two weeks, working full time, on an isolated network. Using the
fog open source cloning solution. Several hundreds of GB transferred
during tests, for cloning 100+ machines inside a few labs. Both single
and multicast cloning sessions used. Tested with a gigabit switch and
also with 10/100 switches. Checked both single and multicast, sequential
tests, in parallel, with/without power failures,  with/without several
patches, in many configurations, with lots of kernel parameters, you
name it.

5) The test scenario shows this bug is completely reproducible, 100% of
the time. Without the patch, my kernels always fail. Tested about 20
different versions and none worked. With the patch above, the two
versions always work correctly.

6) A minor detail: patch has a slight offset for 4.15 (2 lines, probably
new comments or code) but works anyway.

This work would be impossible without all the cooperation from the fog
team. Sebastian suggested the patch, and others helped a lot. A big
"thank you" for them!

I wonder when this will be merged in the main kernel. Please, can anyone
help on this?

Regards,
Paulo

Re: [Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Paulo Abadie Guedes]

Hello, I would like to confirm that it's useful to file a new bug for this
issue. For me, the problem I'm having is the same as we are discussing in
this thread. Would it be just a duplicate?

Maybe I'm missing something, because I don't know the details of the bug
hunting process for Ubuntu.

Can you please confirm I should open it?

In this case, I can add a detailed description and dmesg logs, with debug
on and the timeout error message inside.

Anyway, I want to report advances in this problem. I have tested a few
kernels and patches in the last weeks, and have found one combination that
does solve the issue.

I also checked that this patch is not yet merged into the latest vanilla
stable kernel, version 4.15, released three days ago. But it patches and
works also for 4.15, which is just great (at last for me).

Will send the details later (or tomorrow), as soon as I get back to my
computer.

Paulo

[Kai-Heng Feng]

First please file an upstream bug at https://bugzilla.kernel.org/
Product: Drivers
Component: Network

Also, looks like it's a Ubuntu certified hardware, let me ask around.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Paulo Abadie Guedes]

Hello, I am still having this bug. I'm working with several HP machines, with 
the same model as Yngvi. Here it is (from dmesg messages):
Hardware name: HP HP EliteDesk 705 G3 Brazil Desktop Mini/8266, BIOS P26 Ver. 
02.03 12/22/2016

Interesting to notice that it always happens with a 10/100 switch, but
never occurs with a gigabit one.

I've compiled and tested the 4.15.0-rc8 release candidade, which has the
commit 4419bb1cedcda0272e1dc410345c5a1d1da0e367, but it does not solve
the issue. I added a few printk and can see that the module is correctly
compiled and loaded, but my machine is not a Dell. Hence, the "if"
condition fails and the body is not executed.

I tried also to force the patch, by keeping the "if body" and removing the 
condition, just to see what happens (with another printk to prove that it 
runs). The code runs (limiting MRRS t0 2048, I think), but it does not solve 
the bug. 
It complains that TSC is unstable, right after tg3 breaks. Here is a dmesg 
snippet, maybe it helps.


<...>
[  155.816404] clocksource: timekeeping watchdog on CPU0: Marking clocksource 
'tsc' as unstable because the skew is too large:

[  156.323144] clocksource: Switched to clocksource refined-jiffies
<...>

If you want to take a deeper look, there are a few logs here. Tried also
with "tsc=unstable" and other boot parameters, mostly to see if any
would help (feeling lucky, perhaps?). Nothing changed, the bug is still
in here. They show mostly the same messages, to me.

Well, any ideas? I can reproduce the problem 100% of the time. Would you
like me to test any other patch?

Kai-Heng Feng, you mention "it's better to ask HP and Broadcom to fix
the issue". I agree, but how can we do that?

Thank you,
Paulo

[Kai-Heng Feng]

Take a deeper look, I don't think [1] will help the situation. It's for
mainly to solve the issue on jumbo frame.

I thinks it's better to ask HP and Broadcom to fix the issue.

Can you try it without the if block?

If you don’t know how to compile kernel, I can build kernel package.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Paulo Abadie Guedes]

Hello, I have seen the exactly same issue, with the exactly same
hardware you have: it's the HP EliteDesk 705 G3 Desktop Mini.

I've tested already a ton of options, including recompiling the latest
kernel, booting with several parameters, and so on and so forth. Got
nothing more than a big headache. I have 100+ machines to install in a
month and my team is having a really hard time to deal with this issue.

I have posted my findings on the fog forums. Fog is an open-source
cloning tool. Please check it out:

https://forums.fogproject.org/topic/10731/crash-due-to-timeout-in-tg3
-kernel-module-tg3_stop_block-timed-out-ofs-4c00-enable_bit-2

Any ideas on this bug? It seems to be related to 10/100 switches. If
both ends are gigabit, it works much more reliably. Problems still
arise, but much less frequently. With my old "fast ethernet" switch, the
problem alwasy happens.

It's lurking anywhere between the binary blob (the firmware), the kernel
driver, the hardware or any tricky combination of these. Perhaps related
to the AMD platform

I can run tests or gather more data, if it helps. The issue always happens here.
Any ideas on how to solve or workaround this issue? Patches or parameters are 
welcome...

Regards,
Paulo

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Yngvi Hrafn Pétursson]

Having same same issue on HP EliteDesk 705 G3 Desktop Mini (W4V44AV)
Broadcom Corporation NetXtreme BCM5762 Gigabit Ethernet PCIe (rev 10) and tg3 
module

Error is triggered after the link speed is set or negotiated to 100Mbps
Usually within 15sec of ping ower 100Mbps link
But but works ok with 1Gbps links.

Can be triggered by pluging to 100Mbps port, changin the switch port to 100Mbps 
or:
# ethtool -s eno1 speed 100 duplex full autoneg off

Netboot works until the tg3 module takes ower.
Windows works ok.
Tested:
- multiple cables, computers and switch vendors
- upgrading bios
- ethtool disable eee and hardware offload
- ubuntu 12.04 - 17.04
- new kernel linux-generic-hwe-16.04-edge Version: 4.11.0.14.22
- disable power management in bios
- disable power management with grup switches
- iommu=soft iommu=on iommu=off
- disable highdma

None of the workarounds that i found on Google worked for me.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[luc]

hi guys,
Not a fix but it did the trick: add to your grub iommu=soft.
You will have a fully working ethernet connection...without reduce the speed.
Mine look like this = GRUB_CMDLINE_LINUX_DEFAULT="iommu=soft"
After you have to update grub, like you know.
Why?
Because of this lines with DMESG after i updated my bios (BIOS L06 v02.28 
02/07/2017)=

FWIW, I can't reproduce the issue on the same chip. I used iperf instead
of scp though.

[Roger Techima]

Hello,

i am having the same problem in HP EliteDesk 705 G2 Desktop Mini.

I tried 14.04, 16.04 and 17.04 highdma off solution but this didn't
solve the bug for me.

I am running in a 100Mbit network. I noticed that in gigabit seems to
work, but it seems I did not test for enough time.

Best regards,

Roger

  Here is the procedure to replicate the issue because it is hard to
  replicate it under moderate network load.
  
  1. Bootup a machine with a broadcom 5762 NIC (ie. HP DeskElite 705) using a 
Ubuntu/Kubunu Live CD 14.04-15.04.
  2. from another machine: start 5 sessions, repetitively copy (scp with public 
key authentication) a 70 meg file back and forth to the tg3 machine in each 
session. (not sure if this is necessary)
  3. create a 1GB file on the tg3 machine, with something like dd 
if=/dev/urandom of=/my/test/file bs=1024 count=$((1024*1000))
  4. from another machine: repetitively scp copy that 1GB file from the tg3 
machine. This can be done with something like:
  
  while [ 0 ]; do
     scp -i /my/scp/private.key u...@ip.of.tg3:/my/test/file /tmp
  done;
  
  Networking will mostly goes offline in about 10-30 minutes.
  
  WORKAROUND: Add udev rule to make the changes permanent in 
/etc/udev/rules.d/80-tg3-fix.rules :
  ACTION=="add", SUBSYSTEM=="net", ATTRS{vendor}=="0x14e4", 
ATTRS{device}=="0x1687", RUN+="/sbin/ethtool -K %k highdma off"

Any fix to this bug?

I have the same problem: Ubuntu 16.04 LTS, kernel: 4.8.0-46-generic.
Same problem in Debian 9 kernel 4.9.

It happened to me as well on Proliant 360 gent 9 Ubuntu 16.04.2 with 
4.4.0-72-generic kernel
ifconfig -a didn't show any eno devices
3 identical servers (HW and SW) had no problem at all
a simple modprobe tg3 command and all eno devices (1-4) appeared

[Daniel]

I am having the issue as well on kernel 4.4.0-66 (x64). Disabling
HighDMA did not fix anything on my end and I cannot figure out what will
trigger the issue. It seems to occur randomly and even if there is no
active network traffic.

[chriscrutch]

Any chance there's been any movement on this bug?  It's really a pain
for me.  Disabling HIGHDMA helped a bit, but now it seems to kick in at
different times.  The bandwidth use doesn't seem to be an issue anymore,
but now it disconnects with heavy data transfer to USB.  It kicks in
when performing large backups to an external hard drive, and when
copying large video files to a SD card attached with a USB adapter.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Lauri Võsandi]

Hello, it seems that while running graphical user interface and highdma
off similar problem persists:

NETDEV WATCHDOG: eth0 (tg3): transmit queue 0 timed out
[...]
irq 18: nobody cared (try booting with the "irqpoll" option)

After that device goes offline and can'be brought up again with
rmmod/modprobe and the mouse movement becomes jerky. The problem appears
quicker if you play around with Firefox etc. Tried booting with irqpoll,
the connection still drops but module can be reloaded and mouse isn't
jerky. I tried this with 3.18.25 and 4.4.2 kernels, both exibited
similar behaviour.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Christopher M. Penalver]

** Description changed:

  The tg3 broadcom network driver that binds with chipset 5762 goes
  offline and unable to recover (even with tg3 watchdog timeout) when
  network transmit is under high load.  Then this happens, only a reboot
  would be able to fix it.  Sometimes, however, bringing the interface
  offline and online (via ifconfig) would recover networking.  I've also
  tested with the latest tg3 driver (dec 2014 version) and networking is
  still problematic.I have also disabled TSO, GSO etc... with ethtool
  and the bug still surfaces.  This bug may be related to the integrated
  Firmware.
  
  Here is the procedure to replicate the issue because it is hard to
  replicate it under moderate network load.
  
  1. Bootup a machine with a broadcom 5762 NIC (ie. HP DeskElite 705) using a 
Ubuntu/Kubunu Live CD 14.04-15.04.
  2. from another machine: start 5 sessions, repetitively copy (scp with public 
key authentication) a 70 meg file back and forth to the tg3 machine in each 
session. (not sure if this is necessary)
  3. create a 1GB file on the tg3 machine, with something like dd 
if=/dev/urandom of=/my/test/file bs=1024 count=$((1024*1000))
  4. from another machine: repetitively scp copy that 1GB file from the tg3 
machine. This can be done with something like:
  
  while [ 0 ]; do
     scp -i /my/scp/private.key u...@ip.of.tg3:/my/test/file /tmp
  done;
  
  Networking will mostly goes offline in about 10-30 minutes.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Toan]

It is confirmed, disabling HIGHDMA fixed the NIC problem.  This was
tested by putting a system under load for 120+ hours, and simulated over
12TB of data through the tg3 NIC.  Great find Lauri, and thank you
again!

Thank you for your valuable finding.  I'll test your suggestion in the
next few days to confirm that it works.


I've also reported the work-around to Broadcom dev team and suggested a patch 
to the tg3 driver to disable highdma.  I'll keep you updated on the issue... 
thank you once again.

[Bug 1447664] Re: 14e4:1687 broadcom tg3 network driver disconnects under high load

[Toan]

Lauri,


Can  you let me know if you've tested the work-around solution on a 64bit or 
32bit OS?  AFAK, HIGHMEM option only allows dma support on 64bit system (>4GB), 
so I dont think it would make a difference if the native OS is 32bit.  The 
reason I am asking because I've tested the bug on both 32 and 64 bit systems, 
so I just dont see how disabling highdma on a 32bit system would resolve the 
issue.  Regardless, I will try the work-around solution on a 32bit system 
pretty soon.

[Lauri Võsandi]

Hi,

I am running on 64-bit system. The machine didn't hiccup in ~36 hours so
we stopped testing there, otherwise I managed to bump into connection
drop within hours, 8 hours tops. For test I had scp copying data inbound
and outbound and in addition to that Youtube was playing in several
browser tabs. Higher memory usage seemed to trigger the bug faster.

added following udev rule to make the changes permanent in
