Still present in 3.3-rc4; I've bisected it back to this commit:

commit 92feeabf3f673767c6ee4cfc7fc224098446c1c1
Author: Matt Carlson <mcarlson@broadcom.com>
Date:   Thu Dec 8 14:40:14 2011 +0000

    tg3: Save stats across chip resets

and sure enough, just reverting this single commit on 3.3-rc4 fixes the
problem.

I don't see anything incorrect about the patch.  I'm guessing the patch
just changes the timing somehow.

tg3_reset_chip() does not take any driver-internal spinlocks.  That
happens at tg3_close().  I'm guessing the spinlock in the trace is coming
from synchronize_irq().

If you can't figure it out, we need to revert, so send me a revert patch
as soon as possible.

Are you dealing with a bcm5700 or bcm5701 device?  If so, can you try
the following patch?

Subject: [PATCH 1/1] tg3: Fix tg3_get_stats64 for 5700 / 5701 devs

tg3_get_stats64() takes tp->lock when dealing with non-serdes bcm5700
and bcm5701 devices.  However, functions that call tg3_halt() have
already acquired tp->lock.  When tg3_get_stats64() is called in
tg3_halt(), deadlock will occur.

This patch fixes the problem by separating the stat gathering code into
a new tg3_get_nstats() function.  tg3_get_stats64() is recoded to call
this function and take tp->lock.  The code that takes tp->lock in
tg3_calc_crc_errors() has been removed.  Function signatures have been
cleaned up too.

Yes, this is it:

Well, the patch needs some attention:

  CC [M]  drivers/net/ethernet/broadcom/tg3.o
drivers/net/ethernet/broadcom/tg3.c: In function 'tg3_get_estats':
drivers/net/ethernet/broadcom/tg3.c:9882: warning: 'return' with a value, in function returning void

It also didn't apply incredibly well (the fuzz factors and line offsets
are a lot higher than they should be):

patching file drivers/net/ethernet/broadcom/tg3.c
Hunk #1 succeeded at 7886 (offset -115 lines).
Hunk #2 succeeded at 7908 (offset -115 lines).
Hunk #3 succeeded at 9845 (offset -278 lines).
Hunk #4 succeeded at 9854 (offset -278 lines).
Hunk #5 succeeded at 9873 (offset -278 lines).
Hunk #6 succeeded at 9958 (offset -275 lines).
Hunk #7 succeeded at 10007 with fuzz 1 (offset -275 lines).
Hunk #8 succeeded at 10103 with fuzz 2 (offset -2096 lines).

but it seems to work.

Thanks,

James

I think Matt did the patch for the net-next tree.  Here's the same patch
for the net tree which is the correct tree for this patch.  Thanks.


Subject: [PATCH net] tg3: Fix tg3_get_stats64 for 5700 / 5701 devs

From: Matt Carlson <mcarlson@broadcom.com>

tg3_get_stats64() takes tp->lock when dealing with non-serdes bcm5700
and bcm5701 devices.  However, functions that call tg3_halt() have
already acquired tp->lock.  When tg3_get_stats64() is called in
tg3_halt(), deadlock will occur.

This patch fixes the problem by separating the stat gathering code into
a new tg3_get_nstats() function.  tg3_get_stats64() is recoded to call
this function and take tp->lock.  The code that takes tp->lock in
tg3_calc_crc_errors() has been removed.  Function signatures have been
cleaned up too.

Applied, thanks everyone.

3.3-rc6: Reported regressions from 3.2

[Rafael J. Wysocki]

Hi all,

It looks like many people have switched away from the kernel Bugzilla
after the kernel.org outage and they are using various means of reporting
(and tracking) kernel bugs.  For this reason, it's becoming increasingly
difficult for us to track all of the possible sources of reports and we
are not aware of a number of them as a result.  To tackle this issue we
kindly request that regression reports be CCed or forwarded to the LKML
as stated below.

Thanks,
Rafael

-----------------------------------------------------------------------------

This message contains a list of some regressions from 3.2,
for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.

If you know of any other unresolved regressions from 3.2, please let us
know either and we'll add them to the list.  Moreover, when you are
reporting a kernel regression, please send a CC of your report to the LKML
(or forward it to the LKML if you are not reporting the regression by e-mail)
with the word "regression" in the subject, as that will make it much
easier for us to find it.  Also, please let us know if any of the entries
below are invalid.

Each entry from the list will be sent additionally in an automatic reply
to this message with CCs to the people involved in reporting and handling
the issue.

[ adding Nikolai to CC ]

Nikolai already submitted a fix for b4b583d4e here: 
http://www.spinics.net/lists/linux-input/msg19542.html

I will be queuing that shortly, and will try to make sure that it makes it 
into 3.3 still (otherwise 3.3-stable).

Duncan, I'd be interested whether it fixes the issue you are reporting as 
well.

Thanks,

Just finished testing.  Confirming.

3.3-rc6 unpatched (still) bad,

3.3-rc6 with that patch applied, good.

Works in 3.3-rc6. The patch is like a workaround if understand correctly 
but it cures the problem.

This has been fixed by commits 2885e25c422fb68208f677f944a45fce8eda2a3c
and 29bb5d4fd3140a7d5d02d858118c74a45f15c296, plus probably one more
that I can't identify.
