           Summary: SDL game teeworlds crashes in
                    r100_cs_track_texture_check
           Product: Mesa
           Version: 7.10
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/Radeon
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: alkisg at gmail.com


The SDL-based game "teeworlds" crashes on a laptop with Radeon IGP
330M/340M/350M [1002:4337] when KMS is used, but it runs fine when I use
"nomodeset".

When I don't have "firmware-linux-nonfree" installed the game also doesn't
crash but it's 20 times slower, about 1 fps.
I tested on many recent Debian and Ubuntu versions - the output below is from
Debian testing (Wheezy). I had to comment out "options radeon modeset=1" in
/etc/modprobe.d/radeon-kms.conf for "nomodeset" to take effect.

I can attach more output upon request, or test with different software
versions.
Thank you.
