This can be removed from the regressions list as the issue was already
present in earlier kernels. Sorry for not replying to earlier mails, but
I wanted to check that first and did not find the time to do so until now.

I'll try to find the origin of the issue and update bugzilla with that info.

It's a one-off crash that hasn't happened since I reported it.
And the fact that it happended while I was running 2.6.26-rc3
may just be coincidental and/or caused by temperamental HW.

My intention was never to classify this as a regression, I
just wanted to report a failure data point in case a pattern
emerges.

http://www.kerneloops.org/search.php?search=sky2_mac_int

shows that it happened around 2.6.23-rc1 era once as well...
but not more than that.

That almost makes it look like a hw issue, and very unlikely as a
regression.

I agree, right now I upgraded to the latest git on thursday, and
performed a suspend to see if it would appear, but nothing.
I did notice the same error while doing a reboot, and noticed
appletouch was motionless until I removed and inserted the module back
in.

O.K. I seem to be confused with the sequence:
 List of quirky USB devices.  Please keep this list ordered by:
 * 	1) Vendor ID
 * 	2) Product ID
 * 	3) Class ID

should I use this:

 { ATP_DEVICE(0x021a, 0x05ac), .driver_info = USB_QUIRK_RESET_RESUME },

or this,

 { USB_DEVICE(0x05ac, 0x021a), .driver_info = USB_QUIRK_RESET_RESUME },

can you verify for me so that I don't get things messed up.

Is this a statistically significant number of tests? How often did you see
the appletouch problem? Can we consider this regression to be fixed by
this patch?

[CCed Johannes since we discussed the original problem in a separate thread]

Oliver,

Is the RESET_RESUME quirk needed in addition to the Novell bugzilla patch?

I tried the bugzilla patch which fixed "mouse completely broken" after
resume, but the mouse now behaves strangely - it warps to random
positions whenever you remove your finger from the touchpad.  I did
not apply the quirk.

I also did not get an oops here.

You need both.

Yup, I booted the wrong kernel before, sorry for that.  I'll test again shortly.

Just curious, why is the reset quirk is needed since <= 2.6.25 worked fine?

I don't know. I suspect it is related to timing and you are just vastly
unlikelier to hit the issue under < 2.6.25.

Yeah that jives with my unsuccessful bisection attempts.

At any rate, I retested and the reset quirk does indeed fix the regression for
me as well.  Thanks!

Hello; I would have to say this regression would be fixed from a point
of having appletouch not spit out so many messages;
as for the regression to be completly fixed "it's tough to say", when
I dmesg | grep appletouch I see this:

[   14.811186] appletouch: Could not do mode read request from device
(Geyser Raw mode)
[   14.811186] appletouch: probe of 1-2:1.1 failed with error -12
[   15.045637] usbcore: registered new interface driver appletouch
[   17.153191] appletouch: Geyser mode initialized.
[   17.153191] input: appletouch as /class/input/input9
[   23.563768] appletouch: incomplete data package (first byte: 2, length: 4).

Now keep in mind, from my perspective maybe this is caused by
appletouch not properly configured i.g.
whenever I was using xorg 7.1 appletouch worked great (two and three
finger tap, scroll), but as soon as I loaded xorg 7.3,
the only function I have is two finger scroll.(still need to figure

So maybe having xorg.conf not proper is resulting in this from above.
(but then again could not have anything to do with the above.)

Ahh I give up, I don't know what to say now, after a reboot I see this:

[   17.609756] usbcore: registered new interface driver appletouch
[   18.123672] appletouch: Geyser mode initialized.

What happened with this issue?

It is currently listed as 2.6.26-rc regression.
Is this correct?

And if this patch is required it might not be a good idea to allow the 
use to disable the new code.

The patch listed above works for me, passes rcutorture, &c.  However,
I never have been able to reproduce the original problem, so cannot say
whether it qualifies as a fix.

I doubt very much RCU was the reason of this problem.

Alexey, how did you trigger this problem?

Oleg.

Although I very much appreciate your confidence in my code, it is new
code, so therefore under suspicion.

> Alexey, how did you trigger this problem?

One of them involved running LTP while doing 170 kernel builds in
parallel.

My gut feeling is that find_pid_ns oops, __d_lookup oops and
__call_for_each_cic oops are the same bug.

And rcutorture failures I've mentioned to Paul privately.

Oleg, debugging you've posted never triggered.

kerneloops suggests that I'm alone. :-(

Yep, running rcutorture in parallel with LTP, which didn't reproduce
for me either.

Did the patch at http://lkml.org/lkml/2008/5/28/16 help?

Assuming that the above patch didn't help...  As a desperation measure,
I could suggest the following patch.

And the repeat-by is simply running LTP in parallel with rcutorture?
This is a one-hour run of rcutorture or thereabouts?

Should we mark PREEMPT_RCU as BROKEN for now? I don't know if anybody 
really enables it, but it might be a good idea to make sure people don't 
do so thinking it's good..

If that is the right thing to do.  I would feel better about it if I
could reproduce the failure.

Is there some configuration thing that might make it happen for Alexey but 
not for you? The only obvious one is the normal PREEMPT thing, but 
PREEMPT_RCU obviously depends on that, so there must be something else.

CONFIG_SMP? CONFIG_NO_HZ? CONFIG_[RT|FAIR]_GROUP_SCHED? There's a number 
of config options that change scheduling details..

The only way I can "fix" rcutorture here is SMP=n (not maxcpus=1!).

Among things tried and do not matter are NO_HZ, HIGH_RES_TIMERS, turning off
debugging options (one by one and in bulk), DEBUG_PER_CPU_MAPS, HZ tweaks,
SCHED_MC.

All of this doesn't help, but SMP=n does.

I am running SMP=y without seeing the problem.

Attached is the compressed config file I used for a run on a POWER
machine.  I have used similar config files for x86.  For this run, I built
LTP, installed it, started rcutorture, ran LTP, then ended rcutorture.

The only other thing I can think of is that Alexey's machines are
somehow managing to nest NMIs or something.  I can produce a fix for
that, but have no way of testing it.

Thoughts?

* bug is reproduced on another box with the very same symptoms:
  SMP=y, maxcpus=1 kernel occasionally fails, SMP=n is fine.
  Also Core 2 Duo, x86_64 [1]

  Race is wide -- 60 seconds of rcutorture is enough.

So far tried without effect:
	not doing SMP-alternatives
	NO_HZ=y/n
	HIGH_RES_TIMERS=y/n
	compiling with gcc 3.4.6/4.1.2
	different HZ
	s/asm/asm volatile/g at percpu asm code and PDA asm code
	turning on and off varying CONFIG_DEBUG_ options
	CONFIG_DEBUG_PREEMPT
	softlockup on/off
	making x86_64 cpu_idle() same as 32-bit one wrt rcu_pending et al
	sched_setaffinity() in __synchronize_sched doesn't fail

Probably forgot something, but not a single thing that can remove the
bug in SMP=y case.

Using SMP percpu stuff for UP case miserably failed because of some hard
hang due to incomplete patch, but I still leave this for doomsday.

I'm going to try 32-bit setup and reading rcupreempt disassembly with
microscope.

Very odd how you can reproduce it - now on two machines - but it doesn't 
seem to happen for others. You've tried different compilers, you've tried 
different config options, what the heck is left?

And it's not like Core 2 Duo is an "odd" setup. Even any timer differences 
should have been largely flushed out with HIGH_RES_TIMERS=y/n.

Is there *anything* odd about those machines?

The PREEMPT_RCU thing? I've reproduced it. It hits lockless pagecache,
but I've also reproduced the same problem in dentry cache shrinking.
I'm sure it is a free-before-grace bug.

I've been using DEBUG_PAGEALLOC to make it easier to spot.

Good point!!!  Would either you or Nick be willing to send me either
the vmlinux or a disassembly of the relevant portions?

This is interesting.  The bug occurs on a single CPU, so the bug cannot
involve memory ordering (because CPUs see their own accesses in order)
or preemptions from one CPU to another (as there is but one CPU).

It might involve ordering issues in __rcu_read_lock() or
__rcu_read_unlock(), though the code generated by gcc version 4.1.2 is
ordered correctly on x86.

The code for raw_smp_processor_id() differs in the two cases, but should
give zero in all cases either way, given that there is but one CPU.
Locking goes awayin SMP=n, but the grace-period code disables irqs,
which should act as a good and sufficient lock in the single-CPU case
either way.

This is rcutorture by itself, or in parallel with LTP/kernbench?

(I have mostly been running on 4-CPU boxes without failure either way,
so will try a dual-CPU box.)

FYI, i've been running rcutorture for days on lots of testboxes ranging 
all across the x86 spectrum from single CPU, through dual-core, to 
dual-socket, dual-socket HT, 8-way and 16-way - both 32-bit and 64-bit 
x86.

Not a single failure has been detected in thousands of bootups of random 
kernels (rcu-preempt + rcutorture was a frequent combination tested). I 
added a WARN_ON() to rcutorture failures so it should show up very 
clearly.

This makes me suspect that it might be some special environment issue - 
gcc for example. I'm using gcc 4.2.2 on most of the testboxes.

And running rcutorture overnight on an Opteron system (9.7M updates) showed
no failures.

Maybe this is a stupid suggestion, but SLUB _is_ involved here (in
poisoning the object when it is freed). Do you have SLUB_DEBUG_ON=y or
did you check whether it matters if you have these options on or off?

2.6.26-rc7-git2: Reported regressions from 2.6.25

[Rafael J. Wysocki]

[Note to bug reporters: If you can, please always add
kernel-testers@vger.kernel.org to the CC lists of your reports, as that will
help to filter them out of the other LKML traffic.  Also, if you report a
regression, please add '[regression]' or something similar to the subject.]

This message contains a list of some regressions from 2.6.25, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.25, please let me know
either and I'll add them to the list.  Also, please let me 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.
