10de:0a75 [Sony VAIO VPCF11KFX] Xorg freeze

[Serge Hallyn]

Binary package hint: xorg

Laptop (using nouveau drivers and compiz) was humming along nicely, then
froze - I could move the mouse but keyboard and mouse clicks were ignored,
and cpu usage must have been high as the fan got very loud. The Xorg.0.old
logfile (about to be attached) shows

[ 1375.742] [mi] EQ overflowing. The server is probably stuck in an infinite loop.

100% CPU's resources are reserved to xorg while frozen, mine Xorg.0.log.old shows similarly:

[ 4311.812] [mi] EQ overflowing. The server is probably stuck in an infinite loop.

I'm using current nvidia driver 260.19.12 from repositories. Xorg freezes completely randomly, at least once a day.
It didn't happen before Maverick.

[Matthew Geier (matthew-sleeper)]

I also had random 'freezes' of the GUI. The system was still running, but the X session - frozen,

Nothing in the syslog, dmesg or X.org log.

I did notice when the VirtualBox modules loaded it complained about a NMI watch dog and 'performance counters'.

 I removed the vboxdrv module (rmmod vboxdrv) and the random freezes stopped. No reboot or log out or anything. With the module in place the UI would freeze for 10s of seconds every few minutes. With the module unloaded the machine has been happy for over an hour.

 What I haven't done so far is reload the module and see what happens.

 I'm running VirtualBox from Oracle's repo and not the OSE version as the original poster appears to be, but there may be a connection.

[Tony Wang (wwwjfy)]

Thanks, Matthew Geier. That works for me.

I met the problem when I disconnected an external monitor after using it like one day, but not "random".

[Marcus Thiesen (marcus-thiesen)]

I completely deinstalled all of vbox, but that did not solve the problem for me.

The freezes are not completely random though, because it happens at latest after two hours of constant use.

[Mathieu Laurent (mla)]

I have the same bug. Since the upgrade to Maverick my X freezes randomly. The mouse cursor is still moveable, but the rest of the screen shows otherwise no reaction. I'm using nouveau.

01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 330M] (rev a2)

I just added this line in grub.conf

nouveau.noaccel=1

And not yet freeze ;-) I touch wood ;-)

[Mathieu Laurent (mla)]

I have always the bug. X freeze, I can only move the mouse cursor.

Do you know a way to kill xorg (Alt + SysRq + K doesn't work) ? and how to debug this problem ?

[Mathieu Laurent (mla)]

Similar symptom here :

https://bugzilla.redhat.com/show_bug.cgi?id=618143

[Stephan Müller (megandy)]

I think that this bug is not nouveau specific as it appears also on my t60 laptop with a ATI Mobility Radeon X1400-128MB graphic card. This happens mosty when the system is under heavy load. Sometimes I manage to switch to a console with ALT+STRG+F1 and kill Xorg (with sudo pkill Xorg). It will be restarted automatically, but the session is gone of course. Sometimes it's even not possibly anymore to switch to a console. Then only a hard reset helps.

[Mathieu Laurent (mla)]

Crash again. I can retrieve the error in xorg.log with alt-sysrq commands

[Chris McDermott (ctmcderm)]

Same problem (EQ overflowing. The server is probably stuck in an infinite loop) with nouveau on nVidia GT216 [Quadro FX 880M] using Ubuntu Maverick 10.10. Does anyone know whether there's a workaround to this issue? When the freeze occurs my only course of action is to AC cycle my laptop. I'm not using vbox.

[Tony Mansson (tony-mansson)]

Same problem on core i5 with amd64 Maverick. Did not happen on Lucid.
Happens every three hours or so. Maybe always when in Firefox?
Xorg log says:
"EQ overflowing. The server is probably stuck in an infinite loop."
Same Backtrace as above.
dmesg says:
how_signal_msg: 18 callbacks suppressed
npviewer.bin[3191]: segfault at f1829054 ip 00000000f61bdec3 sp 00000000fff63320 error 4 in "libflashplayer.so[f5e1e000+b2e000]"

Thank you for taking the time to improve Ubuntu by reporting this bug. This appears to be a duplicate of bug 553789.

[penalvch (penalvch)]

Serge Hallyn, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect 660273

[Serge Hallyn (serge-hallyn)]

No, this issue is fixed, thanks.

For what it's worth, I was having similar problems, and had almost concluded it was time to change an admittedly old computer (9-10 years). I had decided it was the graphics card overheating. As a last ditch attempt, I took the card out and gave it a thorough clean. This was a good month ago and I've had no problems since... Rudimentary, but effective.

Right, my laptop definately still overheats, and often (watching the
separate cpu and nvidia temps) it does seem to be the graphics card.
However, it doesn't freeze like it used to. It just overheats and
then shuts itself down :(

[penalvch (penalvch)]

Serge Hallyn, as an off-topic discussion, as discussed in https://wiki.ubuntu.com/Kernel/Debugging/HighTemperatures#Working_around_overheat many have successfully managed overheat (myself included) by governoring their CPU to powersave via a terminal:
sudo cpufreq-selector --cpu=0 --governor=powersave && sudo cpufreq-selector --cpu=1 --governor=powersave && sudo cpufreq-selector --cpu=2 --governor=powersave && sudo cpufreq-selector --cpu=3 --governor=powersave && sudo cpufreq-selector --cpu=4 --governor=powersave && sudo cpufreq-selector --cpu=5 --governor=powersave && sudo cpufreq-selector --cpu=6 --governor=powersave && sudo cpufreq-selector --cpu=7 --governor=powersave

I've had on my todo list for a while now to expand on, and section this off into it's own Community article dedicated to managing Overheat (versus debugging which would imply code improvement). I may have some time within the next couple weeks to work on it.
