Bug#452739: Crash



Hi Brice,

1. The crash is not easy to reproduce. It occurs once or twice a day
   on Debian unstable, all packages upgraded on 20071203.

2. I have not switched between "text" VTs and X VT before a crash.

3. "page table error" appears only after a crash.
   Now I realize that the log file I had supplied is from gdm
   restart attempt after a crash. I am searching how to disable
   gdm automatic restarts. I will supply more information
   if I catch a crash and its log file.

How to allow gdm startup at boot and disable gdm or X.org
restarts after a crash?

Moshe.

 The attached Xorg.0.log is the same as in the previous report, but
this time with details about the crash towards the end.

Would it give more info if I had the -dbg package installed?

This is not a crash (segfault of the X server or so), this looks like a
lockup (the server is stuck somewhere and stop processing anything
else). So -dbg would probably not help, unless you can catch a segfault
with gdb.

I tried to downgrade xserver-xorg-video-intel to 2.1.0-2, but I get a
conflict with xserver-xorg-core. Can someone suggest an
xserver-xorg-core-version I can use with 2.1.0-2, and where to
download that?

You probably want 2.1.1-4, it is available from
http://snapshot.debian.net/archive/2007/09/17/debian/pool/main/x/xserver-xorg-video-intel/
You won't have to downgrade xserver-xorg-core if you take this one.

It this problem easy to reproduce? Did you switch to/from a virtual
console right before it happened? You seem to have some VT switch
related messages in your log.

It is not even sure that the "page table error" is related to the
problem. Can you check whether the "page table error" appears when the
lockup occurs and not earlier?

Brice
