11.4 - deadly crashes: "exception Emask 0x32 SAct 0x0 SErr 0x0 action 0x

Hello,

I have an Inspiron 1764 laptop with
Linux linux-vp82.site 2.6.37.6-0.5-desktop #1 SMP PREEMPT 2011-04-25 21:48:33 +0200 x86_64 x86_64 x86_64 GNU/Linux

Installed 11.4, with all updates applied.

With 11.3 on the same laptop I got from time to time an X-server crash. This was more often with 11.4, but still bearable.
Then came complete crashes (system didn’t react anymore, apparently dead), where a coloured blinking mosaic showed
up. Finally I got today two further such complete crashes (no reactions anymore), this time with completely blank
screen. So it seems getting serious.

From these two last crashes here are the log messages from /var/log/messages (around the places which seem
related):

Anybody any idea?

Hi,

it continues to crash; any help would be highly welcome.

There are three types of crashes:

  • The “dizzy screen” crash: only the screen shows flicker, while the system still runs (and thus,
    using ctrl-alt-del plus return one can shutdown the system; that is, it used to be like that,
    but now the KDE login screen doesn’t allow keyboard control, only the mouse, and that
    doesn’t work; only the power-button helps here).
  • The “blinking screen death”: screen shows a coloured mosaic, partially blinking, system apparently
    completely dead.
  • The “dark screen death”: screen dark, all dead.

Today I had another blinking screen death, after suspend-to-RAM; /var/log/messages contains

Jul 20 13:16:25 linux-vp82 smartd[2068]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 118 to 119
Jul 20 13:56:08 linux-vp82 kernel: imklog 5.6.5, log source = /proc/kmsg started.

Jul 20 13:56:08 linux-vp82 kernel: 22.450278] type=1400 audit(1311166562.71

At 13:16:25 it was still running, and I guess the 13:56:08 message relates to the rebooting, so no message, just sudden death.

Another reboot, directly after the Suse boot menu, resulted in the dark screen death, and again no traces in /var/log/messages.

Hi Oliver,

I have just seen your first post and had a look round, I cannot find the exact
specs for that machine but the errors suggest that there could be something
amiss with your SATA controller, there are plenty of reports that if it is a
micron SATA controller it does not play very well with certain drives and
the only way around it is to either change the drive model/manufacturer or
disable the controller which I realise is not an option on a laptop.

Off the top of my head I would suggest you try and see if there is any way to
change the settings in the bios to see if it makes any difference.

If it is set to AHCI then see if you can change it to “SATA” “legacy” or
"IDE Mode"or whatever.

Not having much luck finding anything about the bios options for that model
so you will just have to experiment.

I take it you have the latest BIOS?

Another thought: (gosh 2 in one day )

try issuing the command:

lspci -vv

so we can see what is actually in the machine and also I want to see what
the interrupts are, there are reports about sharing the SATA irq’s with
others like onboard nic can give these symptoms.

If there are any conflicts you could try the boot param of:

irqpoll

Hello,

I waited a bit, but it seems that one of the installations by chance made the problem go away:
for two days no more crashes yet. Perhaps laptop-mode-tools, though not activated, had an
effect?

Okay, today I had another dark screen death, but that was after awaking from hibernation, and hibernation
has now major problems (it worked with 11.3), so I assume that is a different issue.

Thus I avoided to send more information (more noise). I hope the problem is gone now.

By the way, the BIOS is up-to-date (though I never noticed any change after any BIOS-update).

It might be that the crashes happened with kernel
Linux linux-vp82.site 2.6.37.1-1.2-default #1 SMP 2011-02-21 10:34:10 +0100 x86_64 x86_64 x86_64 GNU/Linux
and then update to
Linux linux-vp82.site 2.6.37.6-0.5-desktop #1 SMP PREEMPT 2011-04-25 21:48:33 +0200 x86_64 x86_64 x86_64 GNU/Linux
happened via installation of laptop-mode-tools, and that cured the problem (hopefully).
Via Yast, installation of new kernels always happens by-the-way, as unnoticable as possible, and it seems that Yast
also has no record on these things (at least not visibly), so kernel-changes happen in a rather hidden way.

Anyway, let’s hope the best, and thanks for your replies!

Sigh, the blinking screen death returned. I just had a happy dream of a joyous live with my laptop, and then it
happened, out of nowhere …

Can’t detect anything in /var/log/messages, but who knows, perhaps you can (at 19:49:12 and somewhat later it
was still working, I just opened something; due to “15000 characters” I’ve capped the file):

Hi,

over the weekend there were no further dark/blinking screen deaths, so let’s forget for now about that.
However the X-server crashes (that is apparently the meaning of the “dizzy screen crash”) continue:

Suspending-to-RAM once typically works, but then the second time the X-server crashes.
Since the screen is dysfunctional, all what I can do is to shut down. But is there a possibility
to restart the X-server? I’ve heard about Ctrl-Alt-Backspace, but that is just a no-op. Shall
I configure something?

Better, how can I avoid the crashes at all?

Should I start a new threat, for “X server crash after suspend-to-RAM”?

Oliver

Hello,

after a few days of peace, I just had another crash:

Now I use kernel-version

> uname -a
Linux linux-vp82.site 2.6.38.8-0.5-desktop #1 SMP PREEMPT Fri Jul 29 00:59:42 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

and that might have changed a bit: before I had the dark screen death (just black screen) and the blinking screen death (blinking
coloured pattern), in both cases apparently the machine dead (no sign of activity, no reaction to anything), and in both cases
also no traces in any log-files. Now I got the same sudden death, but now a black screen with a few red squares on it.
One might consider this as a kind of synthesis (the abyss and the chaos sublimated in a reawakening of suprematism),
so I will try a higher kernel version, hoping for a revelation. Also as before, the death was repeated on the second(!) rebooting.

Let’s see.

Oliver

Just a quick update:

newer kernel version


kullmann-0:~> uname -a
Linux linux-vp82.site 2.6.39.3-0.5-desktop #1 SMP PREEMPT Sun Jul 31 02:04:11 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

But again there was a sudden death with few red squares; /var/log/messages says nothing:

At around 14:00 the crash happened.

Oliver

Hi,

I’m not an expert on this. I know CPU’s can get pretty hot.

Device: /dev/sdb [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 119 to 123

Is the HDD supposed to work at temperatures beyond 100°C i.e. 123°?
I’m not sure if there is a relation but if yes, it might be worth a try getting the temperature down.

rds

kasi

According to
Hot Drives: Dealing with SMART data on OpenSuse 10.3 | Late Night PC
these aren’t real temperatures, and reading the temperatures via smartctl yields


root-0:kullmann> smartctl --all /dev/sda
...
194 Temperature_Celsius     0x0022   119   095   000    Old_age   Always       -       28
...
root-0:kullmann> smartctl --all /dev/sdc
194 Temperature_Celsius     0x0022   120   109   000    Old_age   Always       -       30

So I think the disk temperatures are really okay (also it feels like that).
And actually both disks (internal and externals) weren’t working when the crash happened.

Temperature on this machine is kind of a problem, as discussed at
Very poor CPU performance, likely due to bad heat management
but therefore I’m constantly monitoring it, and the cpu-temperature didn’t exceed 84 degree Celsius (and I’m using
an external cooling device).

This type of crash can also happen directly when booting (exactly at that moment, when the screen goes completely
dark — there it can happen that it crashes), and it happened after suspend-to-disk.

So I’m quite sure it is not temperature-related.

Thanks nevertheless.

Oliver

Just had another crash (as usual now, black screen with some read squares, no reaction to anything,
hard disk dead), as usual without a trace (/var/log/messages):

The crash happened around 21:30. This time the machine has been running for several hours, screen turned out and locked,
I hit a key, first second it looked like as usual, and then it crashed.

INTERESTINGLY, it seems always to happen that after the first crash on booting it crashes a second time!
Very short after the boot menu it crashes with the same screen pattern.
Only then with the second boot it gets up. This second crash leaves absolutely no trace in /var/log/messages
(apparently it happens before the logging starts).

Are there other logging files worth to investigate?

To me it looks like a clear software error: it seems not to happen under Windows (I let it run for quite some time,
never a crash), and that it always happens after rebooting seems also to indicate that it’s a software problem.

I noticed that the crash seemed always related to the screen going dark, that is, the crash either
happened after rewaking from Suspen-to-RAM/disk or in connection with the screensaver.

So first I disabled the screensaver (KDE System Settings/Hardware/Screen Saver), but I got another crash.
Then I disabled the automatic dimming of the display, in System Settings/Hardware/Power Management/Power Profiles,
for the profile “Performance” I’m running), and since then I had no crash: For over a week now, and also
Suspend-to-Ram works now without crashing (while before at least with the second time it would crash after
waking up). (Suspend-to-disk just doesn’t work: it never achieves it.)

This night I had the curious event of the laptop by itself performing Suspend-to-RAM: there was a short
power failure, where the Laptop switched to Powersave mode (I guess), which has “Suspend Session”
enabled, and then apparently this setting prevailed also after return of the power.
Looks like a bug to me, but so well. (It would be good if in /var/log/messages we had general informative messages
like “I start now the boot process” or, in this case, “Starting Suspend-to-Ram, because no user-action has been
performed for 10m, and I’m in power-mode Powersave, where automatic suspension has been set.” This
is trivial to do, and would solve A LARGE AMOUNT OF PROBLEMS, for everybody (given that this is done
systematically). Sigh, the problem is of course, that the kernel is written by hackers, who don’t like to speak …)

Now I have the problem that I need to find out how to shut off the monitor manually: After activating the screen saver
(manually), the screen used to go rather dark (though I’m not sure whether this was fully dark), however now it stays
rather bright, you can read a book. Anybody any idea?

free advice: do not select ‘random’ for the screensaver…because it
will eventually find one that does not like your system, and causes a
crash, freeze or some other strange problem…

i prefer “blank screen”…suggest you pick one, and stick to it…see
if that helps at all…

I already only use the blank screensaver (never could stand that noise created by any
other screensaver).

And perhaps the screensaver is not the problem: Okay, I didn’t try to have screensaver
activated while automatic dimming deactivated, whether this might also cause the
crash. I (somehow) guess that’s not the case, and that the screensaver is not guilty here.
(Trying this out takes possibly some time, and moreover, it interrupts my computations.
And then, due to these many errors in KDE, after restarting most windows are lost or
redistributed to other desktops, and the settings for Konsole-windows are lost, …
so it always takes at least 10m after a restart to get back to a not completely unreasonable desktop.)
