           Summary: xserver crash with compiz when mipmaps are enabled
                    (intel i915 driver)
           Product: Mesa
           Version: CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Keywords: have-backtrace
          Severity: critical
          Priority: medium
         Component: Drivers/DRI/i915
        AssignedTo: dri...@li...
        ReportedBy: vin...@gm...


Using the kernel modules from current drm-git (xserver, libdrm and mesa all
from git HEAD as of 20071217), I can reproducibly crash the xserver by running
compiz with mipmap enabled and simply running any effect involving mipmaps
(e.g. with the default Ubuntu configuration with the "Application Switcher"
plugin enabled, a single "Alt-Tab" is enough to crash the whole xserver).

My hardware : Intel GMA 3100 (G33) using 'intel' driver and EXA acceleration
Software : Ubuntu (amd64) git HEAD xserver, drm and mesa

I'm attaching backtrace and logs to this report.
