Xorg.o.log

I am the current maintainer of a java application that uses OpenGL via the JOGL bindings (http://sourceforge.net/projects/fgflightplanner).  This app crashes with the following message in the console when using the latest Radeon driver under Fedora 12:
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.

dmesg has the following 2 entries:
[drm:r100_cs_track_check] *ERROR* [drm] No buffer for z buffer !
[drm:radeon_cs_ioctl] *ERROR* Invalid command stream !

If I boot with radeon.modeset=0, the application runs (but not well, always on top of everything)

The application is a mature app and runs well with other drivers (fglrx) and on other platforms.

I am using Fedora 12 with all the latest updates:
$ uname -a

This is an issue in the Mesa driver or in the kernel, not in the X driver.

probably same as bug 23532.
