Description pankaj pandey 2009-07-06 11:26:59 UTC 
Description of problem:
With updated F11, i cannot run blender. It causes complete system hang, requiring hard reboot.
Initially i noted this in a comment in bug #507282, but this issue is unrelated to that so i'm creating a new bug report. I found out similar other issues but none too close to this one.

Version-Release number of selected component (if applicable):
Fedora 11 updated, intel 965M laptop, x86_64
xorg-x11-drv-intel.x86_64 2.7.0-7.fc11
mesa-dri-drivers.x86_64 7.6-0.1.fc11

Steps:
1. open terminal
2. Type "blender"
Observation:
1. Terminal shows information upto got python, (/usr/bin/blender: line 61: [: too many arguments)
2. Blender window tries to open
3. Before anything is displayed in blender xserver hangs
4. With mode setting enabled: mouse cursor also stops
   Without kernel modesetting (nomodeset kernel parameter set): xserver still
hangs but cursor still moves (not that it is of any use)
5. I could not check if the computer is still running (ssh) as i
do not have access to another networked computer nearby. Note that the blender
lockup problem occurs irrespective of whether compiz is enabled or not.
Hard reboot is necessary to use the computer again  

How reproducible:
Always

Additional info:
The following info was obtained in /var/log/messages following crashed with kernel parameter drm_debug=1:

Apart from blender, an other application based on vtk also hangs, though that is not so reproducible

I have no xorg.xonf file.

As a workaround to this problem i have found that installing driconf and making some changes in it made the crashes go away. I could also run blender. Here's my driconf file

[pankaj@localhost ~]$ cat .drirc 
<driconf>
    <device screen="0" driver="i965">
        <application name="Default">
            <option name="force_s3tc_enable" value="false" />
            <option name="no_rast" value="false" />
            <option name="fthrottle_mode" value="1" />
            <option name="always_flush_cache" value="true" />
            <option name="early_z" value="false" />
            <option name="always_flush_batch" value="true" />
            <option name="bo_reuse" value="0" />
            <option name="texture_tiling" value="false" />
            <option name="vblank_mode" value="1" />
            <option name="allow_large_textures" value="1" />
        </application>
    </device>
</driconf>

With this setting i get following messages on my terminal when i run any 3d app
[pankaj@localhost ~]$ glxgears 
flushing batchbuffer before/after each draw call
flushing GPU caches before/after each draw call

If needed i can try each setting one by one to exactly determine which one makes the problem go away
Thanks
