Hi,
I have a Radeon Mobility LY (AGP) 32 MB running with
XFree.4.2.0 and linux kernel 2.4.17. After recompiling
kernel with appropriate options, I got OpenGL, DRI and
Acceleration work well, as shown by glxinfo or
gears/glxgears. Nevertheless, programs that use
textures still have rendering problems, i.e. the
program can runn but the texture is displayed with
transparent areas (see attached picture). Running gdb
on the demo program /usr/X11R6/bin/reflect gives me the
following :

---------------------------------------
Starting program: /usr/X11R6/bin/reflect
(no debugging symbols found)...[New Thread 1024 (LWP
1528)]

Program received signal SIGFPE, Arithmetic exception.
[Switching to Thread 1024 (LWP 1528)]
0x405526ff in gl_test_os_katmai_exception_support ()
from /usr/X11R6/lib/modules/dri/radeon_dri.so
---------------------------------------

I get the same output for a program of my own that also
uses textures, but it doesn't even start. Do you have
any idea what this "katmai" is and what it can be due
to ? I use no special config options in my XF86Config-4
file.
Looking forward for your help, R.G.
