Can you include the complete output of /var/log/messages?  The
attached one appears trimmed down.  It is useful to see the whole
thing since the boot of the hung instance.

Also include the output of "lsmod" from a running X session (prior
to crashing).

After doing that, try using the following in the device section of
the config file:

    Option "noaccel"

Does this option improve the stability at all?  If so, we can
explore some other troubleshooting directions to try and narrow
the problem down further.

That was the entire /var/log/messages.	Here is /var/log/messages.1, hope this

Comment 7 Rob Murphy 2004-01-20 02:53:21 UTC
OK, I've been running with the Option "noaccel" for 12 hours or so and
so far I've had no crashes, whereas before I'm sure I would have had
at least one.  So that seems to have helped for the time being, other
than X feeling very sluggish...  

Comment 8 Mike A. Harris 2004-01-20 03:19:35 UTC
Ok, we can both narrow the problem down now, and also improve
performance by doing the following:

1) Run "man XF86Config", and look at the various 'XaaNo.....' options

2) Edit X config file, and comment out the noaccel option used

3) Try the XaaNo options one at a time, and start up the X server
   between each change.  Do whatever it was that triggered the
   crash previously, and try if possible to narrow things down to
   one or more XaaNo options that work around the problem.

That will narrow the problem down to a specific codepath which is
causing the problem, and I can then check XFree86 CVS for fixes
in this area, and in the mean time disable the faulty codepath
for this specific GPU.
