           Summary: OpenGL screensaver 'lattice' provokes driver crash
           Product: xorg
           Version: 7.4
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: oyvinst at ifi.uio.no
         QAContact: xorg-team at lists.x.org


When activating screensaver 'lattice', either by previewing in the Gnome
screensaver preferences or executing the binary directly
(/usr/lib/xscreensaver/lattice), Xorg immediately freezes/crashes every time.
Machines needs to be rebooted, SSH does not seem to work after crash (probably
hard hang). It does not matter whether Compiz is enabled or not (happens with
Metacity as well).


This error message is hard to produce because of the immediate crash, but I
managed after some attempts. Here it is:

$ /usr/lib/xscreensaver/lattice
*********************************WARN_ONCE*********************************
File r300_state.c function r500SetupRSUnit line 1907
Don't know how to satisfy InputsRead=0x00000008
***************************************************************************

And then complete freeze.


- Jaunty beta (tracking/current)
- Using radeon Xorg driver (xserver-xorg-video-radeon 6.12.1-0ubuntu2)
- Kernel linux-image-2.6.28-11-generic 2.6.28-11.41
- Mesa 7.4-0ubuntu1
- Xorg 7.4~5ubuntu18
- libdrm2 2.4.5-0ubuntu4

Hardware:
- ATI X1400 Radeon Mobility, 128MB RAM
- Intel Core Duo 2GHz, 2GB RAM

Will attach Xorg.0.log, kernel log and output of lspci. The Xorg config file is
uninteresting since it does not contain anything (default).

This bug was originally reported downstream here:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/361649

Kernel log:
http://launchpadlibrarian.net/25488287/dmesg.txt

lspci:
http://launchpadlibrarian.net/25488303/lspci.txt

Xorg log:
http://launchpadlibrarian.net/25488314/Xorg.0.log

Or would you prefer I attached these files directly to this report ?
