           Summary: random freeze in ioquake3 like games
           Product: xorg

          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

Games on ioquake3 engine (OpenArena, Quake 3 Arena) randomly freezing X server.
After that, X does not respond to any keyboard shortcuts (Ctrl-Alt-Bksp), the
only way is Alt-SysRq-K (Alt-SysRq-R also works, but I cannot switch consoles,
the screen freezed with game). Console is unusable after that, and I do reboot
with ctrl-alt-delete. While rebooting, artifacts on top of screen can be
visible.
I cannot catch bug myself, but seeing it periodically once per 3-5 days (with
regular system reboots), so can't reproduce it manually.

I'm using Mesa-git, xf-video-ati-6.12.4, libdrm-2.4.18 and kernel 2.6.32
without KMS enabled.
System: AMD Athlon 5200 with ATI Radeon X1600 chipset (r300)
