2.6.12 breaks 8139cp

2.6.12 breaks 8139cp

[Pierre Ossman]

Upgrading from 2.6.11 to 2.6.12 caused my 8139cp network card to stop
working. No error messages are emitted and everything seems to work
(from the local computers point of view). But nothing can be recieved
from the network.

Since 8139cp.c hasn't undergone any significant changes between the
versions the bug must be in something related. Any ideas?

You might post a little more information (i.e., the 2.6.12 dmesg and
possibly a diff vs. 2.6.11).  My guess is something's busted with its
IRQ.

dmesg:s included. But they don't really differ more than some cosmetic
changes in the output strings.

The problem is I can't find anything that differs. 2.6.12 behaves more
or less like someone cut of the rx pins in the connector. ifconfig
doesn't report any errors so it isn't a problem with packets getting
dropped. tcpdump only shows the outgoing packets.

Any more ideas on what I should examine to find any differences?

    As this shows on the 2.6.11 dmesg, and doesn't show on 2.6.12, could
be the cause of the problem.

    Although 8139cp calls pci_enable_device correctly, it may be worth
to try the pci=routeirq thing and see what happens.

    Cheers,

Felipe Damasio

Your 2.6.11 dmesg mentions the VIA IRQ fixup, but the 2.6.12 one
doesn't.  I bet something's broken there.

Can you try the attached debugging patch?  And please collect the
output of lspci, too.

I tried the attached patch and it had no effect. I also tried porting
the 2.6.11 way of handling the VIA quirk but it didn't have any effect.
I'll try a more complete port tomorrow (it was a bit of a hack this time).

2.6.11-mm4 doesn't work. So i'm guessing 2.6.11 wont work either which 
may be why backporting it's via fixes didn't do anything.  I'm gonna try 
vanilla and if that by some crazy chance works, then it'll be fairly 
easy to see what change did it since mm has a nice Changelog.

Re: 2.6.12 breaks 8139cp

this is in the changefile to 2.6.11.   This seems to be the real 
culprit.  I guarantee you if this patch is reverted, there will be no 
problems.

Sorry, i'm retarded, i pasted the wrong changelog line.

	[8139TOO]: Use rtnl_lock_interruptible()
	
	The 8139too thread needs to use rtnl_lock_interruptible so it can avoid

This seems to be the only patch that contains a change to the 8139too code between 
working and non-working code.

nothing in mm's patchset seems to have anything to cause these problems.

Please verify that reverting this patch actually fixed your problem.

$subject talks about 8139cp, but you list a change to 8139too, which are 
two different drivers.

It's often wrong to focus on the driver.  If a driver suddenly stops 
working, that may indicate a problem in the interrupt subsystem, etc.

2.6.11 works fine here so if you're having problems with it I'd say
we're experiencing two different bugs.

It seems that whatever is causing the bug i'm seeing was a change that 
involved the network driver/interrupt subsystem and not actually the 
8139too driver, this was done at around 2.6.3-2.6.4.   A NAPI patch that 
was introduced at that time basically reverted the interrupt function 
and removed the poll functions from the driver (via not enabling napi in 
Kconfig).   I have patched 2.6.12.1 with the NAPI patch and it works.  
Now i just have  a problem with messages about "Badness in __kfree_skb 
at net/core/skbuff.c:290" coming from the changes i made in the 8139too 
driver flooding my logs.  (very bad but also helpful)

That narrows it down, but i was unable to clean up the kfree errors.

Re: 2.6.12 breaks 8139cp

[Pierre Ossman]

Hmm... it seems that TPM has something to do with the bug. Not sure why
though, can't see anything TPM related in dmesg. If I disable the TPM
parts in kconfig then the network works just fine.

I'm going to do a test of 2.6.12-rc1 through rc6 today to see where the
problem appears.

Confirmed this behaviour. The problem appears in rc1 (where the TPM is
added). Unloading the module doesn't help, once it has been present the
system needs a reboot for the network card to function properly.

I don't really see how the TPM can screw things up for the network card
but I'm guessing it breaks something in the chipset (the TPM module gets
loaded for the LPC bridge).

(added TPM maintainer and list as cc)

Re: 2.6.12 breaks 8139cp

[Kylene Jo Hall]

I believe that the reason that unloading the module does not help is
because the module_exit is calling pci_disable in the tpm_remove
function.  I'll generate a patch to remove this.

Additionally this version of the driver  was doing a bunch of stuff to
the LPC bus that I have since found not to be necessary and removed in
patches that have been applied to the mm tree and were pushed to
mainline this week.  Can anyone verify if this is still happening with
the -mm patch?

Kylie

Thanks. I've tried the patch and everthing seems to work fine now. :)

(btw. does no output in dmesg mean that no TPM chip was found? it seems
to have found a pci id it likes atleast.)

True I think if a chip is found there should be info in dmesg.  Are you
loading tpm_atmel or tpm_nsc?  You can look at /proc/misc or see
if /sys/class/misc/tpm0 exists.

Do you know if your machine has a TPM?  Is it activated in BIOS?

Thanks,
Kylie

I'm using tpm_atmel (its PCI id list matches my LPC bridge). Nothing
shows up in /proc or /sys though.

Haven't the slightest. :)
My BIOS is barely advanced enough to configure the clock. So no fancy
stuff like enabling/disabling parts of the hardware. ;)

Can you narrow this down to a fix that's reasonable for -stable?

I'll be sending two patches to fix this problem.  The first one just
changes a bunch of #define's to named emums.  The second is the real
fix.  This was the easiest way for me, let me know if this is not ok.

A problem was reported that the tpm driver was interfereing with
networking on the 8139 chipset.  The tpm driver was using a hard coded
the memory address instead of the value the BIOS was putting the chip
at.  This was in the tpm_lpc_bus_init function.  That function can be
replaced with querying the value at Vendor specific locations.  This
patch replaces all calls to tpm_lpc_bus_init and the hardcoding of the
base address with a lookup of the address at the correct vendor
location.

Thanks Kylene.  Looks like it's just no longer deleting tpm_lpc_bus_init.
So with that nice changelog, I think we'll just go with the full version.
Sorry for the extra work, I thought there might be a simple method by
passing lo/hi and doing tpm_read_index in tpm_lpc_bus_init to set base.

thanks,

I'll be sending two patches to fix this problem.  The first one just
changes a bunch of #define's to named emums.  The second is the real
fix.  This was the easiest way for me, let me know if this is not ok.

Hi there!
I'm seeing the same problem with 8139cp (everithing seems fine, mii-tool
works, but only seldom packets are received from the device). Last good
kernel for me was 2.6.11-bk4. I tried pci=routeirq on 2.6.12, but made
no difference. Here's lscpi output (on 2.6.11-bk4).

Attached dmesg for a working (2.6.11bk4) and a non working kernel

Kind regards,
    Roberto Oppedisano

PS: attached dmesg shows a tainted kernel; the problem is exactly the
same also with a vanilla kernel (whitout ever loading slamr module).

You have a VIA device with dev/function == 0, so 2.6.11 will do the
VIA IRQ fixup for all devices.  2.6.12 will do it only for VIA
devices.  Can you try the attached patch for debugging purposes?

Re: 2.6.12 breaks 8139cp

[Ed Sweetman]

Note: this is not with 8139cp, but with 8139too, particularly 8139b

in 2.6.12, 2.6.12-mm1 and 2.6.12-RT-V0.7.49-01
With preempt enabled/disabled/rt/voluntary...
With mmio and pio in 8139too , with old rx reset and combinations of 
enabled and disabled

Even changed ethernet cables ... nothing stopped my Tx problems.
This is all occurring on a box that until yesterday, had an uptime of 
over 410 days on 2.6.0-mm1, so it's not the hardware, also, reverting to 
that kernel remedied the problem.

Here is a snip from dmesg

NETDEV WATCHDOG: eth0: transmit timed out
eth0: Transmit timeout, status 0c 0055 c07f media 00.
eth0: Tx queue start entry 78  dirty entry 74.
eth0:  Tx descriptor 0 is 0008a03c.
eth0:  Tx descriptor 1 is 0008a03c.
eth0:  Tx descriptor 2 is 0008a03c. (queue head)
eth0:  Tx descriptor 3 is 0008a03c.
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

I'm not sure if this is exactly related to the thread, but it seemed too 
much of a coincidence to think that it's not. 

The symptoms of the problem is short bursts of traffic with 30 second or 
so pauses of absolutely no response, repeating. The higher the bandwidth 
the worse the situation, but it occurs regardless. 

No other errors are reported or seen on the box except this Tx problem.  
I'm tempted to go ahead and try 2.6.11, but haven't yet.

Please do.  If 2.6.11 works and you have any VIA devices,
please also try the 2.6.12 patch from earlier in the thread
and see whether that helps.

Thanks!

it's a via motherboard, so yes, i'll be trying that patch if 2.6.11 does 
work.  It seems to make sense to try the patch first, but i had already 
removed the 2.6.12 trees i had compiled before that patch was posted.  
It takes a while for this computer to compile the kernels so i'll report 
back tonight ...  in any case, if the patch doesn't work, i'll move up 
the rc for 2.6.12 until the problem occurs, figure out what happened 
with the 8139 drivers in that patchset and hopefully see a fix. But 
first, a concert to goto.

has anyone had their problem fixed by the patch to 2.6.12?

Hi!
I applied your patch to a vanilla 2.6.12.1 kernel and the card is still
not working.
Attached dmesg with and without pci=routeirq.

Kind regards,

Ummm.  I was involved in this.  Here is the 'final' post after Mr Hirofumi 
found the cause of my issues:

http://www.ussg.iu.edu/hypermail/linux/kernel/0402.3/1709.html

But I looked at what he said and found the real problem on my system (after 
all that):
