Fatal server error:
Caught signal 11.  Server aborting

----
When running under mmio-trace, no output is there, and get this error:
libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering
2 frames in 13.3 seconds =  0.150 FPS

The whole system becomes very slow, to the point where you'd think it is frozen.

Comment 2 Alexandru Botezatu 2007-05-15 11:09:45 UTC
