[BUG] bisected: PandaBoard smsc95xx ethernet driver error from USB timeout

[Frank Rowand]

Hi All,

Not quite sure quite where the problem is (USB, OMAP, smsc95xx driver, other???),
so casting the nets wide...

The PandaBoard frequently fails to boot with an eth0 error when mounting
the root file system via NFS (ethernet driver fails due to a USB timeout;
no ethernet means NFS won't work).  A typical set of error messages is:

[    3.264373] smsc95xx 1-1.1:1.0: usb_probe_interface
[    3.269500] smsc95xx 1-1.1:1.0: usb_probe_interface - got id
[    3.275543] smsc95xx v1.0.4
[    8.078674] smsc95xx 1-1.1:1.0: eth0: register 'smsc95xx' at usb-ehci-omap.0-1.1, smsc95xx USB 2.0 Ethernet, 82:b9:1d:fa:67:0d
[    8.091003] hub 1-1:1.0: state 7 ports 5 chg 0000 evt 0002

[   13.529998] IP-Config: Failed to open eth0

I have bisected this to:

     USB: EHCI: use hrtimer for the I/O watchdog

Note that to compile this version of the kernel, an additional fix must
also be applied:

  commit ba5952e0711b14d8d4fe172671f8aa6091ace3ee
  Author: Ming Lei <ming.lei@canonical.com>
  Date:   Fri Jul 13 17:25:24 2012 +0800

     USB: ehci-omap: fix compile failure(v1)

The symptom can be worked around by retrying the USB access if a timeout
occurs.  This is clearly _not_ the fix, just a hack that I used to
investigate the problem:

  http://article.gmane.org/gmane.linux.rt.user/9773

My kernel configuration is:

  arch/arm/configs/omap2plus_defconfig

  plus to get the ethernet driver I add:

    CONFIG_USB_EHCI_HCD
    CONFIG_USB_NET_SMSC95XX

I found the problem on 3.6.11, but have not replicated it on 3.9-rcX
yet because my config fails to build on 3.9-rc1 and 3.9-rc2.  I'll try
to work on that issue tomorrow.

I play upstream kernel on Pandaboard A1 frequently, looks not
see the failure problem before. Maybe the problem is config dependent.

If you may share your config file, I'd like to do the test too.

I will do a separate reply with the actual config at the point where
the bisect completed.

I create the config for each commit during the bisect with scripts
that do the equivalent of:

  make omap2plus_defconfig

  make menuconfig

    # this allows USB thumb drive
    # Device Drivers -> USB support -> EHCI HCD (USB 2.0) support
    CONFIG_USB_EHCI_HCD=y

    # ethernet device
    # Device Drivers -> Network device support -> USB Network Adapters ->
    #  Multi-purpose USB Networking Framework ->
    #  SMSC LAN95XX based USB 2.0 10/100 ethernet devices
    CONFIG_USB_NET_SMSC95XX=y


Some more random information that may be helpful....

----------
$ cat /proc/cmdline 
ip=192.168.1.85:192.168.1.1:192.168.1.1:255.255.255.0:panda nfsroot=192.168.1.1:/a/target/panda root=/dev/nfs ip=dhcp mem=463M console=ttyO2,115200n8 debug earlyprintk


----------
The percentage of boots that show the problem varies quite a bit between
the kernel versions that I tried during my bisect.  For my first attempt
at bisecting, I decided a version was good if it booted 12 times.  That
bisect failed for various reasons.  For my second attempt at bisecting,
I decided a version was good if it booted 18 times.


----------
There are some timeout messages that I am not positive are symptoms of
the problem.  With these messages, the smsc95xx driver initialization is
successful, so the ethernet device is available.  For the first bisect
attempt, I did not treat these messages as errors.  For the second bisect
attempt I treated these messages as errors.  A typical example of the
timeout message is:

  [    9.537811] hub 1-1:1.0: state 7 ports 5 chg 0000 evt 0002
  [   17.056701] usb 1-1.1: swapper/0 timed out on ep0out len=0/4
  [   17.062652] smsc95xx 1-1.1:1.0: eth0: Failed to write register index 0x00000108
  [   17.070343] smsc95xx 1-1.1:1.0: eth0: Failed to write ADDRL: -110
  [   17.076751] IP-Config: Failed to open eth0

  The mention of swapper is not relevent, it just happens to be the
  current process when the time out occurs.

I have only seen these timeout messages in the boot log, so they may not
be a very visible symptom.  They also _might_ be unrelated to the problem,
but my gut feel is that they are related.


----------
The problem manifests as a timeout from at least two different locations
in drivers/net/usb/smsc95xx.c:

 656 static int smsc95xx_set_mac_address(struct usbnet *dev)
 657 {
 ...
 663         ret = smsc95xx_write_reg(dev, ADDRL, addr_lo);
 664         if (ret < 0) {
 665                 netdev_warn(dev->net, "Failed to write ADDRL: %d\n", ret);
 666                 return ret;
 667         }

751 static int smsc95xx_reset(struct usbnet *dev)
 752 {
 ...
 783         write_buf = PM_CTL_PHY_RST_;
 784         ret = smsc95xx_write_reg(dev, PM_CTRL, write_buf);
 785         if (ret < 0) {
 786                 netdev_warn(dev->net, "Failed to write PM_CTRL: %d\n", ret);
 787                 return ret;
 788         }

There may be additional locations.  These are just two that I captured when
debugging.  Some of the other smsc95xx_write_reg() calls in smsc95xx_reset()
are protected with checks for timeout, with up to 100 retries.  I don't know
if more checks for timeout, or longer timeout, is a solution or just an
incorrect way of papering over the real problem -- this is not an area of
expertise for me.


Thanks,

Frank

Oops, pasted the wrong example.  This is an example of a timeout, but the
driver still works, and the system boots:

  [    6.072357] smsc95xx 1-1.1:1.0: eth0: register 'smsc95xx' at usb-ehci-omap.0-1.1, smsc95xx USB 2.0 Ethernet, fa:50:73:02:79:67
  [    6.084655] hub 1-1:1.0: state 7 ports 5 chg 0000 evt 0002
  [   11.220672] usb 1-1.1: swapper/0 timed out on ep0out len=4/4
  [   18.183441] usb 1-1.1: link qh8-0001/dc8d6640 start 2 [1/0 us]
  [   19.822296] IP-Config: Complete:

Config attached...

3.9-rc2-20130314 doesn't have the problem observed on my Pandaboard A1,
but I only tested booting from MMC, not from NFS.

I don't understand how that commit could cause a timeout unless there 
are at least two other bugs present in your system.

Yes, I would not be at all surprised if this commit merely exposes a
problem in other code.  That is why I included so many different people
and subsystems on the email distribution list.

My PandaBoard builds fail on 3.9-rcX due to ARM multiplatform issues.
Either there is something I need to change about the way I build it,
or it is broken (that is a side issue).  My simple expedient was to
hack around multiplatform, and just make it build (patch below if
anyone else wants a _temporary_ hack).

The problem appears to not be present in 3.9-rc3.  In older kernel versions,
the worst case to see the problem was 18 boots.  For 3.9-rc3 I booted 42
times without seeing the problem.

The problem occurs at least up through 3.8.  I'll try to reverse bisect
between 3.8 and 3.9-rc3 to see when the problem disappeared (I'm running
short of time, so no promises for a near term result).

This patch is a _temporary_ hack, not fit for man or beast.  Avert
your eyes, do not apply to any respectable repository!

This is a known issue and will be resolved the proper way in 3.10.
For 3.9 you could also use a temporary fix posted here

Thanks for the tests. There were a lot of OMAP EHCI related cleanup/fixes [1]
that went into 3.9. It would be interesting to know what fixed it.

I have built 3.9-RC2 for PandaBoard ES and the only problem I have seen is
that you need to add "LOADADDR=0x80008000" when building uImage target.

Yes, that is essentially what my hack patch does.  The result of my patch
is that arch/arm/boot/Makefile is invoked with MACHINE="arch/arm/mach-omap2"
so that at the top of the makefile, the "include $(srctree)/$(MACHINE)/Makefile.boot"
which pulls in the proper values for addresses.
