Update :
still present in 2.6.36-rc4.
However, the call stack is a little different now. As the computer crashes very
soon, I've taken a photo, see attachment.

Update : Still present in 2.6.36-rc5
With the same log as shown in comment #2
Some more info are given after that ("recursive fault fixed, but rebbot is
necessary").
If I wait a little more, I get another pile of messages.

More precisely, the problem occurs indeed after dhcp gets an IP address, and
before (or when) sshd is started. Between the two, I guess iptables rules are
defined in my network scripts.

Well, I managed to boot in single mode, and tried to execute commands one by
one to see what triggers the problems.
Indeed, it's really random, sometime it's while ldconfig is called by the init
scripts, sometime it's when starting udev...
The callstacks are quite different also, sometime it's kmemcheck, sometime
preempt count, sometime NULL dereference...

So I'm posting the dmesg output I saved each time I got an error. Now at least
they are complete, so the root cause may be easier to find.

I'm not sure the second and next warnings are not due to the first one, and a
bug in kmemcheck itself.
I'm totally unable to tell what cause it, and I gave up bisecting because it
crashes here and there, and I cannot say what crash is due to which bug, if
ever there is only one bug.

.config file

I append the .config file, just to tell what are the kernel debug options I
use.
I'm running in 64bit and build from vanilla source, with gcc 4.4.4.

I don't think this is hardware related, since I get the same on my laptop. More
some racy problems in udev/ldconfig/fc-cache

I'm still thinking it's a vfs problem or kmemcheck itself bug.

People may not be paying attention to this due to the subject line.

Except for the initial bug report, none of the other stack traces have anything
to do with ext4/jbd2.    And in the initial ext4 trace, we see the complaint
that we're calling might_sleep() in ext4_mark_inode_dirty(), in a code path
where we are manifestly not taking any spinlocks.    And in fact we don't see
any spinlocks being taken at the point where the complaint is mode in
ext4_mark_inode_dirty().   Yet preempt_count > 1.

It looks to me like some unrelated piece of code is bumping preempt_count, and
not decrementing it.  Maybe in some code which is called from an interrupt
handler, in some device driver?   That might explain why you're getting
failures all over the kernel.

It may be worth closing this report, and opening several new ones, one for each
failure, and make it clear this is not an ext4-related problem, since the
subject line and component assigned for this bug is highly misleading.

Including your kernel config would also be useful when you do that.

See my latest comment here:

    https://bugzilla.kernel.org/show_bug.cgi?id=17361#c14

This subject line is highly misleading, since after -rc4, the stack
traces are in places all over the kernel, in other places other than
ext4/jbd2.  So I fear no one is looking at this bug report given the
highly misleading subject line.

It looks like you have spinlock debugging, and yet there wan't any
spinlocks listed on the initial ext4 might_sleep() warning.  So
something looks highly confused.

The fact that you closed other bugs as duplicates of this one that
relate to kmemcheck makes me wonder if this is really a kmemcheck bug.
(If so, the subject line here is doubly, doubly misleading.)

Do you see any symptoms if you turn off kmemcheck?  Are you sure this
isn't just only a kmemcheck bug?

I just had a quick glance at the report, and here's my gut feeling: I
see perf symbols in the stack trace. I don't think kmemcheck and perf
play nicely together (for example if perf uses NMIs to write data to
its buffers, it could get a page fault inside the NMI handler, which
is not so nice, I think).

Isn't this exactly what Frederic Weisbecker tried to detect and warn
about in a patch that I saw recently?

Please do as Ted suggested and try to turn kmemcheck off.

WTF -- this ended up in a bisect pointing to some PCMCIA patch! Justin:

  * does this happen with wireless-testing.git ?
  * Did you do the bisect on the entire kernel? What git tree are you
using to bisect?

Did you simply bring up the interface and then suspsend? Did you not
add a new interface in between this? ath5k's add_interace has:

        if (sc->vif) {
                ret = 0;
                goto end;
        }

But why does it just allow this to go through without complaining if
multiple vifs are not supported?

I see no updates to this since August. There are boat load of PCMCIA

Pavel already verified the PCMCIA-bigdiff since 2.6.35 does work, so it is
_not_ a PCMCIA issue.

[Bug 17361] Watchdog detected hard LOCKUP in jbd2_journal_get_write_access

https://bugzilla.kernel.org/show_bug.cgi?id=17361





--- Comment #15 from Christian Casteyde <casteyde.christian@free.fr>  2010-10-04 18:48:29 ---
I've explored some of the ideas you mentionned.

First, I disabled kmemcheck, and indeed I've got no warning at all. So this is
really a kmemcheck + something else (buggy driver or perf counters as
mentionned by Vegard in his previous mail).

I could check the reverse: kmemcheck but without perf counters, however I
cannot unselect the perf option on my config (it is forced by something else
I've not found). kmemcheck used to work (I don't know if perf counters were
available in previous kernels however).

Second, I have most of my drivers built in, however I use sound cards as
modules in order to control the load order.

I've booted after erasing the /lib/module driver, but with kmemcheck enabled,
and it was far better. I got only one kmemecheck error:

ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
ERROR: kmemcheck: Fatal error

The good news is all other errors are gone. Here is the lsmod output without
kmemcheck, just to tell the modules that could cause more grief:

no this is the current Linus tree(have not tried any other tree).
as for the unresolved regression, this just was filed a few days ago..

the bisect had to be between 2.6.34 and 2.6.32 due to pcmcia breaking 
after 2.6.34(there is a bug report for that, but got resolved)

the system is opensuse 11.2, I just simply start the machine boot up,
after nm connects I open a terminal then suspend in the terminal, upon 
wakeup this message appears.

yeah the first pcmcia bug I hit with this machine was back in may/june 
ended up doing a bisect for that(which was painful due to a slow 
machine)which ended up getting fixed.(never thought to check s2ram after 
that)

as for bluetooth the only issue I have with that is for my other 
machines which is hitting this: http://lkml.org/lkml/2010/9/1/61
(but have not had a chance to follow through due to doing the update 
broken web addresses in the kernel)

alright if this is with the latest wireless tree, then I can throw that 
in to verify that it is indeed fixed..

And in the initial ext4 trace, we see the complaint that we're calling might_sleep() in ext4_mark_inode_dirty(), in a code path where we are manifestly not taking any spinlocks.    And in fact we don't see any spinlocks being taken at the point where the complaint is mode in ext4_mark_inode_dirty().   Yet preempt_count > 1.

In my experience, this is typically caused by stack overflow smashing the task struct and randomly setting preempt_count to a non-zero value.
