Description Thord Nilson 2009-03-25 14:10:26 UTC 
Ethernet stops working, or wery slow on nvidia "MCP78S [GeForce 8200]
Ethernet (rev a2)" after enough data copied over nfs. On some tests
the kernel panicked. (driver forcedeth)

The machine is an AMD64x4, 2.5 GHz on a ASUS M3N-H/HDMI motherboard.

Problem found on SLAMD64 12.2, kernel 2.6.27.7-SMP (64 bit), slackware
12.1 with 2.6.24.5 and 2.6.28.7 kernels (32 bit).

Machine is connected to a 1 Gbit netgear switch. On that switch is
among other machines two servers, one is an AMD 64x2 2.6 GHz running
slackware 12.0, (first kernel 2.6.21.5 and later 2.6.28.7),(forcedeth
on CK804) the other is a dual celeron 400 MHz running slackware 8.0,
kernel 2.4.32-SMP. (RTL-8139 ethernet)

Problem only seen with NFS so far, small rsize, wsize makes problem worse, 
SCP and SAMBA tested ok. Copy from slow server better than fast.

After copying from 50 to 100 GB over NFS from the AMD server the
network stops working, or sometimes is very slow. Doing an ifconfig
eth0 down followed by an ifconfig eth0 up restores communication for a
while.

I have also tested to change the line "static int max_interrupt_work = 5;"
to  "static int max_interrupt_work = 15;" in forcedeth.c but could not see any difference.

The following NFS tests are with mount options: rsize=8192,wsize=8192

(Note, most of the tests below are only performced once due to the time it
it takes to run them.)

SLAMD64, kernel 2.6.27.7 SMP ==> hangs / slow after 50-100 GB.
Added a script doing "ifconfig down/up" every 5 minutes ==> kernel panic

Removed config option "CONFIG_FORCEDETH_NAPI" ==> kernel panic,
picture of screen can be found on:
http://w1.874.telia.com/~u87421281/panic.jpg

Slackware 12.1 kernel 2.6.24.5 SMP ==> hangs / slow after  50-100 GB.
Slackware 12.1 kernel 2.6.28.7 SMP ==> hangs / slow after  50-100 GB.
used ethtool to disable sg, tco, gso ==> panic

Skackware 12.1 kernel 2.6.28.7 NOSMP ==> hangs / slow after  50-100 GB, also
				hung switch so no machine on it was accesible.

WinXP, SP3 (32bit), copied from celeron server with samba ==> OK.

SLAMD64, kernel 2.6.27.7 SMP, on  RTL-8169 nic ==> OK.

SLAMD64, kernel 2.6.27.7 SMP, MCP78S nic with removed config option
"CONFIG_FORCEDETH_NAPI", copying using scp ==> OK.

Copying using NFS from celeron server ==> OK.

The following NFS tests are with mount options: rsize=1024,wsize=1024

Copying using NFS from AMD server ==> hangs after 7 GB.
used ethtool to disable sg, tco, gso ==> hangs after 3 GB.

Copying using NFS from celeron server ==> have copied 183 GB in 12
hours. 

used ethtool to turn off all options (could not turn off tx) ==>
					copied about 48 GB in 11 hours.

Comment 1 Alan 2009-04-08 09:42:43 UTC 
Seems to be fixed for other reporters in 2.6.29
Comment 2 Thord Nilson 2009-04-12 19:58:14 UTC 
Problem is still there, maybe a little more reproducible and takes a little longer, now about 70GB at small rsize/wsize instead of less than 10GB.
 
I tested with kernel 2.6.29.1, took  .config from slamd64-12.2 2.6.27.7 kernel,
made oldconfig, gave default anwers for all new options.

Tested with the following NSF mount options: rsize=1024,wsize=1024

After about 70 GB copied from NFS server to local disk the network hangs.

Doing an ifconfig eth0 down followed by an ifconfig eth0 up started communication again but after a while the kernel paniced.

See http://web.telia.com/~u87421281/panic1.jpg for a screen image.

Reconfigured the screen to try to get more info from panic.
Repeated the test, hung again after about 70 GB copied network hangs again.

Took some printouts from ifconfig and ethtool (shown below) 
did ifconfig down/up, comm retarts and hangs after a little while, repeated
ifconfig down/up, and a while later the kernel panics.

See: http://web.telia.com/~u87421281/panic2.jpg

Status when network is hung:

Comment 3 Dennis Birkholz (nexxes Informationstechnik GmbH) 2009-06-08 15:31:57 UTC 
I have the same problem with kernel versions 2.6.29.4 and 2.6.27 vanilla + openvz briullov.1 patches so I am now using my old 2.6.21-gentoo-r3 kernel.

For me the problem occurred after copying files onto the server, it hanged after 300MB of files and on 40GB another time.

I have an "MSI K9N Ultra" motherboard with two gigabit "nVidia Corporation MCP55 Ethernet (rev a2)" network controllers.

On my machine found the kernel not panicing but maybe i rebootet to fast with a another kernel version ;-)

Greets,
Dennis
Comment 4 Dennis Birkholz (nexxes Informationstechnik GmbH) 2009-06-08 15:34:50 UTC 
I forgot to mention I tried the tx timeout patch from bug #13258 (on my 2.6.29.4 from kernel.org) but it also does not fix the problem.
Comment 5 David Cureton 2010-04-01 12:57:24 UTC 
I would like to add some more information and possible work around to this issue.

I have been experiencing similar issues on my MythTV frontend ( 2.6.30 custom kernel,  AMD Athlon(tm) 64 X2 Dual Core Processor 4400+, nVIDIA MCP67 PCI bridge and MCP67 ethernet controller. 

The front end is NFS-rooted (no harddisk) and the on-board NIC was hanging at random points and vidio playback sometimes stalling.

For quite some time I have had a realtek NIC in the system to overcome this problem, however I have just revisited this problem with the on-board nVIDIA NIC to get rid for the PCI realtek NIC.  (This point is important to establish that it is the nVidia NIC and not another part of the system) 

Emperically I found that if I kept a constant stream of network traffic addressed to the device the slowness/stalling would subside. The system would behave as expected whilst the receive network activity was active. Removing the network activity would cause the issue to re-appear. 
 
I achieved this network traffic by issueing a flood ping to the network card from another box on the network. (ping -f <ip address of nvidia card> ) 

I have since discovered that disabling MSI interrupts globally also eleviates the issue.  This was acheived by booting the kernel with the "pci=nomsi" kernel option. Since doing so the specific video clip which reliably caused the issue plays faultlessly. (Dont ask me why this video in particular tickled the problem repeatably - no idea) 


Having found the gem that turning of MSI interrupts resolves the problem I looking into the kernel driver and found the follwoing code in the forcedeth driver.  

static void nv_msi_workaround(struct fe_priv *np)


        /* Need to toggle the msi irq mask within the ethernet device,
         * otherwise, future interrupts will not be detected.
         */
        if (np->msi_flags & NV_MSI_ENABLED) {
                u8 __iomem *base = np->base;

                writel(0, base + NvRegMSIIrqMask);
                writel(NVREG_MSI_VECTOR_0_ENABLED, base + NvRegMSIIrqMask);
        }
}

The above code being related to the following forum thread. 

http://kerneltrap.org/mailarchive/linux-netdev/2008/6/7/2060274

It is my hypothesis is that the MSI irq issue is still there in silicon of the MCP67 generation and the 'workaround' does not completely overcome the issue.  By bombarding the interface with inbound traffic I was causing many more RX interupts to occur so the occational missed interrupt does not have any effect which under normal conditions was causing the network instability. 

This scenario would fit my symtoms almost perfectly. 

Maybe disabling MSI irq globally is quite harsh however the system is stable so I will probably leave it in this manner. I think there may be a method to only disable MSI interrupts of a sindle PCI device which may help isolate the issue. 


Please let me know if there is anything further I can add to the bug report that would make it more useful. I am happy to further testing now that I have a repeatable way of causing the issue. 

Regard, 
David
