           Summary: [ati-dri] R100 OpenGL Crash buffer overflow
           Product: DRI
           Version: XOrg CVS
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: redtux2k9@gmail.com


DRI is working with direct rendering and hardware acceleration, but only
working OpenGL application is glxgears and small example written by me using
gtkglext. When I try to run yabause or any application that uses OpenGL then
I've got this:

*********************************WARN_ONCE*********************************
File radeon_swtcl.c function r100_swtcl_flush line 322
Rendering was 13 commands larger than predicted size. We might overflow command
buffer.
***************************************************************************
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See
dmesg for more info.

And then crash.

When I write dmesg I got this:

[drm:r100_cs_track_texture_check] *ERROR* No texture bound to unit 0
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

I'm using module radeon under ATI Radeon M6 (R100) and packages version under
Archlinux i686:

ati-dri 7.8.2-1
xf86-video-ati 6.13.0-1
mesa 7.8.2-1
libgl 7.8.2-1

The DRI module is from 20090101, but was working ok with version from 20061018,
so with Mesa 7.2 (2008).

I've tried to compile Mesa 7.2, but the DRI was not working (only swrast).

Please help me, I can't even watch youtube with proper speed. Only alternative
for me is Debian Lenny that has everything (DRI) working ok, because it has the
old version.
