           Summary: [r600g] crash when using xeglthreads
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: kdekorte at yahoo.com

Using mesa git e7f5d19a1106351f2db8f62f59f51be86eaa93df
kernel 2.6.36 (kernel-
libdrm git
xf86-video-ati git 

I'm able to duplicate a crash in r600g pretty reliably with this command 
./xeglthreads -n 6 -t -l

it gives an error:  r600_priv.h:184: radeon_bo_unmap: Assertion `bo->map_count
>= 0' failed.

works ok with -n values < 6, but real performance drop between 4 & 5
