Bug#364253: xorg: Random crashes on SiS card when switching xsessions
Package: xorg
Severity: normal
Since a month or so, I experience regular crashes of my Debian testing
machine. About one per week, if not more. The crash is related to the
use of Xorg (so my report here), but usually break the whole system down.
Sorry for the length of this message, but I wanted to give you as much
information as I could.
SOME GENERIC REMARKS
====================
- CRASH NEVER OCCURS WHEN THE MACHINE IS UNATTENDED (mine is up 24/24)
or in remote text access (I do remote backups, have a CVS server on it,
and such: never crashed during that kind of operations). That even if
Xorg is running in whatever configuration.
- IT USUALLY CRASH WHEN OR JUST AFTER I SWITCH X SESSION.
I usually run 2 to 4 xsessions in parallel (CTRL-ALT-F7 to CTRL-ALT-F10)
and switch between them using the usual key commands.
SYMPTOMS BEFORE CRASHES
=======================
- Text consoles becomes unreadable. Either the screen is black, only
cursor shown, or strange graphics in black/gray/white filling the
screen. In both case, except of the display, the terminal seems to
be functional.
- Pixmap under X11 are sometimes filled with random data found in
memory. Eg. the KDE bar is filled with what looks like to be some
Firefox page displayed some time ago, or simply random "noise".
- When switching session (by alt-ctrl-Fn) a temporary black screen
appears (not unusual) but there is blue-green dotted cursor as wide
as the screen that can be moved with the mouse. Sometimes the crash
occurs on that screen.
-> Those symptoms can last pretty long before a crash occurs. They
doesnt show up when only one session is openned (and swtiching
to text consoles). Usually opening a second session is enough to
render the text consoles unusable.
LOGS TRACES LEFT AFTER REBOOT
=============================
As the crash of the Xserver render the machine unusable (usually the
kernel is crashed too), there are not much info I have left. But there
are some logs that my be interesting. They are below:
- From /var/log/Xorg.0.log.old
Note: Last crash didnt left anything useful in this log file.
So I pastle an older crash under the same conditions (but from
06/03/04, so likely with a previous Xorg version):

# debian configuration
I run a pretty uptodate and standard debian testing, with a few
unstable pkgs but nothing kernel/xorg related.
Thanks for any help.
