Logs attached (but attaching did not flip the status).
Comment 5 Pawel Salek 2006-02-15 22:18:23 UTC 
I have a feeling it's is a 64-bit issue: software rendering works just fine on a
Athlon+r300 (but hardware acc does not, see a separate report

If I start dri on my IBM thinkpad with radeon mobility M10 and start 
glxgears after one rotation the whole computer hangs and need a powerdown.
Happens every single time.
FYI

Which is unrelated to this report, as this bug is reporting software GL
problems on x86_64.  The problem you are having is due to radeon kernel
module problems, and is unrelated to this.  Disable dri in xorg.conf
by commenting out Load "dri", or by removing the radeon kernel module
from your system and the problem should go away.  If you have problems,
search bugzilla for other bug that is tracking the radeon problem.

Pawel,

Does this problem still occur for you with software rendering on SiS/x86_64
with current Fedora development?
Comment 9 Pawel Salek 2006-03-07 08:39:29 UTC 
Affirmative:
$ LIBGL_DEBUG=verbose glxinfo
name of display: :0.0
X Error of failed request:  GLXBadContext
  Major opcode of failed request:  144 (GLX)
  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  17
  Current serial number in output stream:  17
