Description Arsen.Shnurkov 2009-11-18 10:54:24 UTC
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

Comment 3 Arsen.Shnurkov 2009-11-19 09:35:38 UTC
This bug is reproduced again (with xf86-input-mouse now from git)
Comment 4 Arsen.Shnurkov 2009-11-19 10:29:18 UTC
I add a few lines to config 

Section "Module"

#	Disable  "extmod"
	SubSection "extmod"
	    Option "omit xfree86-dga"


now xserver just hangs after some mouse movement,
but doesn't write anything to /var/log/Xorg.0.log

What makes you think this is a duplicate?  The EQ overflow is a generic symptom that occurs when the server is too busy to promptly handle an event.

Arsen.Shnurkov: I've got a couple of Ubuntu bugs[1][2] with a similar-looking backtrace, featuring miPointerUpdateSprite, also using Xinerama to bind multiple cards together.  They report the problems when the mouse pointer leaves the first screen - is this the same behaviour you're experiencing?

Comment 9 Jeremy Huddleston Sequoia 2011-10-03 19:51:20 UTC
That backtrace is confusing to me.  Can you get a better backtrace with some 
symbol names (or symbolicate the one you have), so we can get a better 
understanding of how you're getting to that point?

Does this reproduce with the 1.11.1 server?

No response.  No usable information.  Closing.
