What do the intel-gfx people think?

====== original mail follows =======
Hi sorry for bothering you once again. 

I noticed most of the issues are coming from drm (I have the stupid "Intel 
Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics 
Controller (rev 03)")

So I checked today the logs again and found out it crashed in the mornign when 
turning on the notebook in the office.

Is there something you can conclude from the trace below and another 
question - why is it checking CRTC as I have LVDS, VGA1 and DVI1 - actually 
using only the LVDS and DVI outputs

Thanks again for taking your time

Testing on latest drm-intel-nightly from

http://cgit.freedesktop.org/~danvet/drm-intel/

If that doesn't help then please boot with drm.debug=0xe, reproduce the
issue and then attach the complete dmesg. Please make sure everything
starting from boot messages is in there, increase the dmesg buffer with
log_buf_len=4M or so if that isn't the case.
-Daniel

Testing on latest drm-intel-nightly from

http://cgit.freedesktop.org/~danvet/drm-intel/

If that doesn't help then please boot with drm.debug=0xe, reproduce the
issue and then attach the complete dmesg. Please make sure everything
starting from boot messages is in there, increase the dmesg buffer with
log_buf_len=4M or so if that isn't the case.

And there's that taint P again due to the vmware modules.

I know that you tried without the vmware modules where your kernel
wasn't tainted but then you got a #GP which could be something entirely
different. But now you're hitting some sanity-checking code which could
mean there's some corruption happening.

So, can you reproduce that exact same warning, i.e. this one:

WARNING: CPU: 1 PID: 4142 at drivers/gpu/drm/i915/intel_display.c:8292 check_crtc_state+0x5cf/0xa60 [i915]()
pipe state doesn't match!

*without* the vmware modules installed?

Also, it wouldn't hurt to try the shiny new 3.12.

HTH.

I looked there, but it would have taken more time then available to get an

Yes with #GP machine locks and this time it didn't

I'm not sure - you know it happens random

I was thinking to do so - but lets be honest. I would save everybody's time if 
I were 100% sure it is a hardware issue and I would buy a new notebook. The 
one was serving great for the past 7y and it payed off itself already long 
time ago.
I could try 3.12 and also try in combination with the git drm-intel as Daniel 
suggested.
I'm still thinking that his has something to do with the graphics, but rather 
guessing from intuition.

I'm not sure if it helps somehow but when I grep as following I find only the 
tainted erros - it's not visible which of them were GP, but still it shows 
where it hit the issue

I looked there, but it would have taken more time then available to get an 
idea on what it is exactly trying to do

Yes with #GP machine locks and this time it didn't

I'm not sure - you know it happens random

I was thinking to do so - but lets be honest. I would save everybody's time if 
I were 100% sure it is a hardware issue and I would buy a new notebook. The 
one was serving great for the past 7y and it payed off itself already long 
time ago.
I could try 3.12 and also try in combination with the git drm-intel as Daniel 
suggested.
I'm still thinking that his has something to do with the graphics, but rather 
guessing from intuition.

I'm not sure if it helps somehow but when I grep as following I find only the 
tainted erros - it's not visible which of them were GP, but still it shows 
where it hit the issue

Hi
I listened to your advise and installed 3.12 kernel (no other modules on top 
that would taint the kernel like vmware/player). 
So it turned out I have to enable /proc/acpi (depreciated) and acpi_cpufreq, 
so that I may have a proper support for cooling and frequency.

$ acpi -t
Thermal 0: ok, 50.5 degrees C
$ acpi -c
Cooling 0: Processor 0 of 10
Cooling 1: Processor 0 of 10
Cooling 2: LCD 3 of 7
$ lsmod | grep cpu
cpufreq_ondemand        8085  2
cpufreq_powersave        926  0
cpufreq_performance      930  0
cpufreq_conservative     6305  0
acpi_cpufreq            6955  0
processor              23167  3 acpi_cpufreq

After doing all of this I was able to reproduce the issue by overloading the 
system with following simple steps:
1. start a compilation of something (ex. kernel)
2. run another process hungry application (flashplayer in firefox)
=> system locks in about 3-5mins

I also noticed that the board gets pretty hot, so in my opinion it locks 
because of thermal issue.
I think this also would explain why I see errors at different processes 
(mostly Xorg), but with 3.12 I do not get any trace message in the log files.
Could you advise which option should be enabled in the kernel or how I could 
log/trace if system locks.
How can I make sure that the cooling/temp works properly?

Perhaps after upgrading in september the system is working under heavier load 
and therefore I started having the issue, or something broke in software or 
hardware and it can not cool down properly. I don't think the kernel is the 
issue, because I had the same with older kernels that were working fine 
before.
The fan looks clean and there is no dust or whatever in the cooling area, that 
would prevent colling. The physical position of the notebook (docking 
station) also did not change.
I don't know where to look at or to start, so any advise is appreciated.

thanks in advance and kind regards

Ha, so we're getting somewhere :)

The symptoms we're seeing so far are very much consistent with a thermal
issue.

Try enabling CONFIG_LOCKUP_DETECTOR, that could tell us where we're
hanging.

But, make sure to be on a console and not in X in order to get a chance
to see the message. What I do is reroute all log messages to /dev/tty8,
i.e. have

*.*		|/dev/tty8

in syslog.conf and switch to it with Ctrl-Alt-F8.

What kind of upgrade exactly did you do to a laptop?

Does the issue happen if the laptop is not in the docking station?

In any case, you need to follow your steps back of the upgrade to have
at least a clue what causes the overheating.

Can you revert the upgrade and see whether it still happens?

Also, do you have sensors support for your hardware? IOW, can you
monitor the temperature of some hardware elements by running

$ sensors

?

For example, I see this on my box here:

$ sensors
fam15h_power-pci-00c4
Adapter: PCI adapter
power1:       45.64 W  (crit = 125.19 W)

k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +19.2°C  (high = +70.0°C)
                       (crit = +90.0°C, hyst = +87.0°C)

radeon-pci-0100
Adapter: PCI adapter
temp1:        +80.0°C

so when something overheats, running "watch -n 1 sensors" could give
some hints.

Also, what does

$ grep . -EriIn /sys/devices/system/cpu/cpu0/cpufreq

give?

Also, can you connect your laptop to a serial or netconsole to collect
dmesg before and while the lockup happens?

Basically, we're looking for a hint about which part of the hw causes
the overheating...

HTH.

this is also true - which makes me sad as the notebook was working great in

I was using debian squeeze with trinity desktop (KDE 3.5.10) and upgraded to

I wanted to test this, but as I have to replug a lot, didn't do it so far, 
also because it was working with this docking station for the past 2y

I could try this. I guess this assumes I have to have another machine running 
in paralell, but this can be arranged with a little effort

Thanks for the hints. As I never had to do with overheating or similar issues, 
your help is very precious to me. Unfortunately we have a little child on 
board and time is limitted :) to a couple of hours daily, where I can work at 
home which means even less time for debugging. But I never give up. I just 
want to be sure that it is not a hardware issue

Thanks again and kind regards. I'll post when I have some useful input

I was using debian squeeze with trinity desktop (KDE 3.5.10) and upgraded to 
debian wheeze with TDE (3.5.13)

I wanted to test this, but as I have to replug a lot, didn't do it so far, 
also because it was working with this docking station for the past 2y

I could try this. I guess this assumes I have to have another machine running 
in paralell, but this can be arranged with a little effort

Thanks for the hints. As I never had to do with overheating or similar issues, 
your help is very precious to me. Unfortunately we have a little child on 
board and time is limitted :) to a couple of hours daily, where I can work at 
home which means even less time for debugging. But I never give up. I just 
want to be sure that it is not a hardware issue

Thanks again and kind regards. I'll post when I have some useful input

Oh ok, so I thought you were talking about a hw upgrade, like adding
more RAM, hew hdd, etc.

Ok, can you try this: boot without X and try overloading the machine on
the console, i.e. do

while true; do make clean && make -j64; done

or similar in your kernel repository. Does it trigger then?

Although I can't imagine how a software upgrade would cause the
overheating... :-\.

You could try booting a distro from a livecd and see any change there...

That's some ACPI timezone thing. So what happens if you do

$ watch -n 1 sensors

and you incur the load? Do you hit the critical temperature?

I wanted to first compile the kernel with the debug option you mentioned, but 
while compiling it went to about 75°C.

That would be too easy and machines would be dying left and right of
overheating. Actually, sane hardware is much more robust than that and
it throttles itself in case of critical temperature levels. And, IMHO
your Dell Latitude D520 should be fine, in that respect. But we'll see.
:-)

Yeah, that's still ok if we trust the output saying that 126°C is the
critical temp.

It would be interesting to see what this sensor says right before the
machine locks up.

HTH.

That would be too easy and machines would be dying left and right of
overheating. Actually, sane hardware is much more robust than that and
it throttles itself in case of critical temperature levels. And, IMHO
your Dell Latitude D520 should be fine, in that respect. But we'll see.

Yeah, that's still ok if we trust the output saying that 126°C is the
critical temp.

It would be interesting to see what this sensor says right before the
machine locks up.

HTH.

I was thinking the same - but started to despair

This test is outstanding for a moment where I have more free time to reproduce 
and log everything

I did something else yesterday evening before going to bed ~00:30
I closed the  notebook cover just so that it would switch off the LCD display
In the morning I opened up and found the notebook with blinking led lights 

http://www.dell.com/support/troubleshooting/us/en/19/KCS/KcsArticles/ArticleView?c=us&l=en&s=dhs&docid=DSN_DBECF64CFEDA449398CB9E859D4944A5

unfortunately I don't find the pattern in the link above
the left one was on and the other two were blinking

Arter shut down (keep power button pressed) and turning it on only the two 
leds (middle and right) were blinking, which according the link above means 

Configuring PCI bridges	Replacing the system board.

After waiting for about 1-2mins notebook starts normally - another link to 
heating issues.

At the moment I have to do pretty much at all levels, so I can not test any 
further.
This is just an update. I'll post again when more results are available.
I'm thinking to open up and inspect from inside - perhaps somewhere the 
cooling system is clogged or something.

regards

Hi again,
sorry for writing  after such long time of silence, but I was busy with one 
project (and family as well)

I was able to solve the issue by removing some of the modules I had in 
xorg.conf.
I noticed that it is not the cpu that is overheating, but rather the 
video/graphic card. The area around the "Dell" logo on the front of the 
display is still pretty hot, but the system seem to be working fine now and I 
can not reproduce the issue any more.
Someone would ask why I'm using the xorg.conf. The reason is because without 
it X automatically loads the GL direver for 3d support and I am not able to 
use second display.
Perhaps it is worth trying latest intel driver as susggested before. However 
with the current one it is working fine, so I would consider the issue as 
solved.

I would like to thank you for your precious support and ideas once again.

regards

Interesting. Which module was that?

It was probably making your GPU go nuts. The more interesting question
is whether this module would behave on your machine normally and only
some buggy incarnation of it would cause the overheating... I.e., it
could be you upgraded X and with the new version the issue started
appearing. Fun.

Sure, you're welcome!
