Are you sure you get it with glxinfo? Or with "cubemap", "texdown"+"b key"? Read the list. It was introduces with the Mesa-4.0.4 to 5.0/5.1 transition (Mesa CVS and DRI). > disabling TCL support Due to your Radeon VE QL (no hardware TCL). > Floating point exception > > GDB sais: > > Program received signal SIGFPE, Arithmetic exception. > [Switching to Thread 1024 (LWP 14835)] > 0x404175c7 in _mesa_test_os_sse_exception_support () from > /usr/X11R6/lib/modules/dri/radeon_dri.so Expected but with the above apps. > and the _mesa_test_os_sse_exception_support() code sais in a comment > > /* Perform an SSE divide-by-zero to see if the operating system > * correctly supports unmasked SIMD FPU exceptions.

Most of us get it with 2.4.19 and 2.4.20+/2.5.xx ;-) > When I compile DRI without SSE it works fine, poor performance, but it > works. You should run with MESA_NO_SSE=1 and get 3DNow!.
