description |
Whilst running an update-manager session for Lucid 10.04 i386 the update-manager appeared to 'freeze' midway. The rest of the Gnome interface was similarly unresponsive and the mouse cursor displays the animated 'busy' circle (but it wasn't being animated).
The system has been working correctly in all other respects so far as I have been able to tell. It is a dual-CPU Asus A7M266D motherboard with two Athlon MP 2000 CPUs.
Connecting over ssh I found an error in /var/log/Xorg.0.log:
Unhandled monitor type 0
disable primary dac
enable primary dac
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

Symptoms: Jerky mouse with no further response from application windows, keyboard input ignored, CPU running at 100%, hard reboot required.
The message "[mi] EQ overflowing. The server is probably stuck in an infinite loop" appearing in the X server's log (/var/log/Xorg.0.log) is a symptom of a number of other bugs. It is *not* a bug in itself.
*** Unless the backtrace in Xorg.0.log is precisely the same as this one, please POST A NEW BUG REPORT with the backtrace ***
Usually all attempts to regain control of the system locally fail - no switching to the other virtual terminals, no ability to kill the Xserver. Remote connections via SSH usually work but the only way to return the system to a usable state is to force a restart (sudo shutdown -r now).
The symptom has been manifesting itself since 2008 (kernel 2.6.25) at least on many different distributions. It is related to the use of DRI and accelerated 3D graphics.
Turning off Desktop Effects (Compiz) can reduce the incidents but other applications that use OpenGL and EXA (such as Firefox, or games like Unreal Tournament) can trigger it easily.
There is a suggestion that using:
export SDL_VIDEO_X11_DGAMOUSE=0
prior to launching SDL applications will avoid the issue but this doesn't help Firefox.

A clear explanation of the report is found in a mailing-list post by Adam Jackson @ RedHat: http://marc.info/?l=fedora-devel-list&m=124101535025331&w=2
" "EQ overflowing" is not a bug, dang it. It's a symptom.
Input events are handled in two places in X. A signal handler reads the
events from the kernel, updates the cursor position, and adds the event
to the queue; and then the main loop drains the event queue, sending
events to clients and possibly updating the cursor image (say, if it
changes from an arrow to a text bar). Since you can't malloc from
signal handlers, the event queue is some fixed (but large) size.
If you run out of space in the event queue, it's because the server is
stuck somewhere away from the main loop. But that's not any one
specific place, that's the entire rest of the X server. You could be
waiting for the hardware to go idle. You could be waiting to acquire
the DRI lock (in DRI1). You could be trying to do some kernel request
that the kernel is taking its sweet time to get around to. _Anything_.
So "EQ overflowing" is not any one particular bug, it's a symptom of
many different bugs."
