Description Bug 2006-10-01 07:48:56 UTC 
git/cvs xserver, radeon, mesa, drm
http://tremulous.net/index.php?section=about

I start tremulous 1.1.0 , play a demo, then press ~ for the console.
at that moment my X700 pcie card seems to hardlock. The screen freezes, with the
console halfway down.

To resolve this situation a reboot is required.

I tried debugging this remotely.
Seems it's not a segfault of tremulous.x86 (gdb reports no crash in tremulous),
but seems a higherup X error.

X process is hanging there, unkillable:
root      1055 55.8  0.8 11104 8020 tty7     R    16:02  10:50 X :0

attached gdb to it:

Can be closed, unsetting "SDL_AUDIODRIVER=alsa" fixed this insane behaviour.
the screenfreeze and X lockup made me suspect it was Xorg hanging on the card or
something.
