I'm using the Xfree version existing in unstable debian (4.1.0-16), X
-version shows 4.1.0.1.

This bug is reproducible between several trees: stable, -ac, -aa1 from
several releases.

Output of lspci -v attached (voodoo 3 pci video board)

I can reproduce the bug (not always but very usual):
-I don't touch anything.
-xscreensaver-gl starts
-_only_, when the screensaver called "stonerview" starts, and after a
while, the image stops, and an oops is generated:

-----------------------------------------------------------------------
---------- ksymoops 2.4.5 on i686 2.4.19-rc1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.19-rc1/ (default)
     -m /boot/System.map-2.4.19-rc1 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

-When i watch the stopped screen, the image _always_ is the same, the
screensaver always stops at the same point Any advices of how to
debug/strace/whatever this?

(after Xfree is hanged, ctrl+alt+Fn does'nt works, so i do sysrq sync +
reboot, but this is normal...)
