Not an mtx bug.

Sysinfo:
Ubuntu 9.10 (karmic) - 2.6.31-19-generic - Gnome 2.28.1
Compaq Evo - Intel(R) Pentium(R) 4 CPU 2.00GHz - Mem 994 MiB
Graph Card : 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device
Audio Card : 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller

I have had to live with this bug for months!

Former messages to ubuntu french forum:
http://forum.ubuntu-fr.org/viewtopic.php?pid=3326591#p3326591

It looks like if some graphic widgets (this morning Gmail pop-ups in Firefox) would bring the system to this freezed state...
alas I can't identify which kind of technology they are made of
No trace at all apparently in system logs...

[saglio (jeanmarc-saglio)]

Sorry, currently my system is upgraded to 2.6.31.22

Additional comments:
- fsck display good results
- in order to reduce pulseaudio memory usage I blocked udev at 147~-6 (Karmic) according recommandation I red

[saglio (jeanmarc-saglio)]

My Firefox extensions are:
Ubuntu Firefox Modifications 0.8
Mediaplayerconnectivity 0.9.3

I succeed to see video without any pb... creating only this trace:
Jun 29 11:05:11 evo21-desktop pulseaudio[1521]: ratelimit.c: 2 events suppressed

Anything looks fine... till next system freezing!

N.B.
Soft shutdown with Alt-Syst R S E I U B
leads me to think that keyboard is always good as hardware...

idem after loading thunderbird

but etherything looks good however !?
... don't know where to look after!

N.B. new keyboard device, but nothing different

[saglio (jeanmarc-saglio)]

Hello world! Is anybody listening?

Does this issue, which appears randomly sooner or later during my sessions, ring a bell to somebody?
Could it be a hardware concern (even if all ubuntu hw tests are passed successfully)?

Today it freezed twice under a Thunderbird activity (reading html texts)
I can see nothing in system logs but :

N.B. I always apply the soft reboot Alt-System R then S E I U B

[saglio (jeanmarc-saglio)]

I had no such problems when I used Ubuntu 8.04, they appeared with versions 9.04 to 9.10, could it be solved with version 10.4 LTS ?

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in xserver-xorg.
For future reference you might be interested to know that a lot of applications have bug reporting functionality built in to them. This can be accessed via the Report a Problem option in the Help menu for the application with which you are having an issue. You can learn more about this feature at https://wiki.ubuntu.com/ReportingBugs.

Also, can you test this with Maverick, to see if the issue is still present?

[saglio (jeanmarc-saglio)]

Thank you for your care.

I'm still with Karmic and... random freezing!
I looked to https://wiki.ubuntu.com/X/Troubleshooting/Freeze

I installed openssh
After system freezed I succeed to login as root
I went to /sys/kernel/debug/dri/0 but all files remained empty in this repertory...

I only could execute dmesg
