Turns out GL is generally broken - glxgears renders with random colors, which alternate whenever it writes the framerate to stdout and GNOME Terminal updates - Nearly every GL xscreensaver either renders wrong, spews endless command stream errors (kernel rejection or possible command buffer overflow warnings), or does both - crack-attack doesn't draw the the play field - celestia crashes at startup, after a predicted size overflow warning and a CS size mismatch warning etc.
Tried updating to mesa 7.6-0.18 from koji, didn't help.
Tried with nomodeset. glxgears rendered correctly, Celestia hard locks the machine, Google Earth causes a panic.
Hi Nicholas, Could you attach /var/log/dmesg after booting with drm.debug=1 as kernel parameter? Could you also try with nomodeset and attach /var/log/Xorg.0.log? I can confirm the R200 glxgears brokenness (it happens with my FireGL 8800/R200 128MB). -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Created attachment 380834 [details] dmesg with drm.debug=1 Xorg.0.log with nomodeset will be coming shortly

Thank you Nicholas. Can you confirm that launching GL applications with LIBGL_ALWAYS_SOFTWARE=1 results in correct rendering? All logs aboard, switching to ASSIGNED. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
glxgears and Google Earth render correctly using software, Celestia still gets a SIGFPE at start up, which I'm inclined to believe isn't Mesa's fault. (Mesa isn't involved in the stack trace at all.)
Huh. Somewhere in all the rebooting, things started rendering correctly again, but with the usual spate of command buffer warnings. I'm also not seeing the glyph cache and/or root pixmap corruption that I saw from time-to-time (and failed to mention in this bug report). Perhaps the result of the mesa upgrade?
Yes likely. Please update everythings and report back if you still see issues or not.
Upgraded to mesa 7.7-2.fc12 and libdrm 2.4.17-1.fc12 -- no improvement.
OK, I rebooted under the assumption that testing from a clean slate would be a good idea and discovered the hard way that my old xorg-x11-drv-ati segfaults with the new libdrm. After updating that to xorg-x11-drv-ati-6.13.0-0.20.20091221git4b05c47ac.fc12.x86_64, X works again. * glxgears still renders with the wrong colors. * googleearth no longer segfaults, but it does exit with drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info. dmesg is: [drm:r100_cs_track_texture_check] *ERROR* Texture of unit 0 needs 131072 bytes but is 32768 [drm:r100_cs_track_texture_print] *ERROR* pitch 256 [drm:r100_cs_track_texture_print] *ERROR* use_pitch 0 [drm:r100_cs_track_texture_print] *ERROR* width 256 [drm:r100_cs_track_texture_print] *ERROR* width_11 2048 [drm:r100_cs_track_texture_print] *ERROR* height 256 [drm:r100_cs_track_texture_print] *ERROR* height_11 2048 [drm:r100_cs_track_texture_print] *ERROR* num levels 0 [drm:r100_cs_track_texture_print] *ERROR* depth 0 [drm:r100_cs_track_texture_print] *ERROR* bpp 2 [drm:r100_cs_track_texture_print] *ERROR* coordinate type 1 [drm:r100_cs_track_texture_print] *ERROR* width round to power of 2 0 [drm:r100_cs_track_texture_print] *ERROR* height round to power of 2 0 [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! * celestia doesn't segfault either, it just exits unexpectedly. errors attached. dmesg is: [drm:r100_cs_track_texture_check] *ERROR* No texture bound to unit 1 [drm:radeon_cs_ioctl] *ERROR* Invalid command stream ! * xscreensavers misrender and spew errors, as per usual

Latest mesa-libGL-7.7-3.fc12.x86_64 fixes the color issues, but celestia and googleearth still blow up (and googleearth's explosion still corrupts the render glyph cache).
Tested with the (updated) September 2010 graphics test day CD live image and the kernel is still rejecting command streams with the R200 T0/T1 GPU hang workarounds.
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This was finally fixed upstream in 43b93fbffc2c080dba2e84df6fce8d7e6c0a2581. F14 is still broken, though.
can you check the F14 kernel in koji? http://kojipkgs.fedoraproject.org/packages/kernel/2.6.35.9/64.fc14/
2.6.35.9-64.fc14 fixes this problem
seems pushed to stable now.
