Description Need Real Name 2001-05-11 16:08:21 UTC
Description of Problem:
When I leave my machine up overnight and I come back to it in the morning,
the X server is messed up (screen flickering) and my log file is filled
with messages from the kernel about drm not being able to free (memory) due
to null pointer.  Eventually my hard disk fills up with these error
messages.  This problem happens consistently when the machine is left
unattended.  Upon reboot everything comes back up normally.

How Reproducible:
Leave the system unattended overnight.

Steps to Reproduce:
1.   Boot system
2.   Leave system running unattended for 8-12 hours

Actual Results:

Expected Results:

Hardware being used:

Intel 866MHz PIII w/256MB RAM

Comment 1 Arjan van de Ven 2001-05-11 16:12:50 UTC
Can you past at least one exact message please ?

Comment 2 Need Real Name 2001-05-11 16:31:24 UTC
I'll send messages the next time it happens.  I rebooted today before saving the
log messages...

Comment 3 Mike A. Harris 2001-05-13 23:16:53 UTC
Yes, please provide the exact kernel log messages from /var/log/messages,
as well as your /etc/X11/XFree86.0.log, and your X configuration files:
/etc/X11/XF86Config and /etc/X11/XF86Config

Comment 4 Mike A. Harris 2001-05-13 23:19:08 UTC
Oops.. I just submitted by accident with a typo.  I need your:

/etc/X11/XF86Config and /etc/X11/XF86Config-4 files.

Comment 6 Mike A. Harris 2001-05-15 10:33:20 UTC
The above file is unuseable to me.  unzip says it is corrupt.
Please in the future, just attach the raw files uncompressed so that they can
be easily viewed in a web browser, or downloaded and saved to disk ready to
roll.  It makes bug report tracking much simpler. I'll look at the files
as soon as you reattach them for me individually and as raw text.
Be sure to choose text/plain when you attach them.

Comment 11 Alexei Podtelezhnikov 2001-05-16 02:36:34 UTC
Someone ( bug 39846 ) told me that mtrr is supposed to be fixed in recent
rawhide from 5/15. Would you 
also test the rawhide kernel from
ftp://ftp.redhat.com/pub/linux/rawhide/i386/RedHat/RPMS before it appears in

Comment 12 Mike A. Harris 2001-05-16 16:05:29 UTC
Yes, this does look like an MTRR problem.  Another point to note though
is that you're using DRI in 1280x1024.  On a 16Mb card, that is greatly
pushing the limits IMHO.  Try 640x480 and see if it works, then increase
the resolution to 800x600, etc..  DRI needs a lot of RAM, just a ballpark
is 4 times the RAM for 2D.  2D needs x*y*fbbpp at a minimum, and double
for double buffering (default).

Comment 13 Mike A. Harris 2001-11-01 03:08:09 UTC
Closing bug, unable to reproduce any problems using a properly
supported configuration for a 16Mb card.  My tests were done
at the maximum supported resolution of 1024x768x16bit with
DRI enabled, using XFree86-4.1.0-3 as shipped with Red Hat
Linux 7.2.

If you experience problems still, while using the latest release,
please reopen the bug report with new information.  Thanks.
